What foods can last 3-4 days without refrigeration?
I'm going to be camping for 4 days at a location without easy access to fire (hence no boiled water). As such, I'm going to be packing a bunch of canned stuff for my daily meals. The place is in England, where we're expecting a few hot days this week and maybe some rain over the weekend.
However, I have some free time before the trip to cook food. But I'm not sure if there's any good foods I could bring along that could keep for 3-4 days without a fridge. I guess that crosses out most meat dishes.
Some ideas I had were: falafel, fritters, bread, calzones, pasties. Have you tried taking such foods camping and if so, did they last a few days without spoiling? Are there any other foods you'd recommend? Thank you so much!
It really depends on whether or not you plan to be pooping during those few days.
Pfft, eat a few MRE's a day and you won't poop for two solid weeks. Emphasis on solid because when that shit comes out it will be a brick the size of a baby.
I can't remember what it's called, but mixing the brownie with the coffee was the best thing I've ever had from an MRE.
It's called ranger pudding and the recipe is 2 packets coffee, 1 packet creamer, 1 packet chocolate beverage powder, 1 packet sugar. Add a bit of water, stir and enjoy. You can also add peanut butter if you're feeling frisky.
Edit: I forgot the 1 packet of crackers. Gotta add those bad boys in for substance.
Thank you! I'm a civi (civilian) and only had it when my older sister came back from basic training.
Ok, I'm googling that shit (no pun intended), didn't know about it.
I wouldn’t have noticed at all if you hadn’t said it
Goes in as an MRE, comes out as an MRE. Efficiency.
Because of a certain YouTuber now every time i see MRE i hear the sound "let’s get this out onto a tray... nice"
Wow I wasn't expecting to get some much info today!
👀
A true sign of a Lemmy old timer. That was what, a month ago now?
At least.
Cup noodles can be made with cold water too. But they will take about 30 mins instead of 2-3 minutes. Tried and tested. They still taste good. They are not very nutritious, though.
I would recommended making Energy Bars/Balls. You can find a lot of recipes online but here's mine:
These can last over a week outside the refrigerator (considering the ambient temperature in your area does not rise above 30° C). And inside the refrigerator they can last for over a month.
You can add different types of seeds, nuts, sweeteners etc, depending on what you like, what your body needs and what's available.
Hope this helps.
Activating your almonds, I see
There's a similar Indian recipe
https://en.wikipedia.org/wiki/Chikki
Yes. They can last for months. But they are relatively hard to make at home. I usually buy them.
I'm over here getting nostalgic for BEANS.
New York City???
Look into backpacking meals. They keep forever practically and simply require heat and water most times to prepare.
Came here to suggest this as well. You said no easy access to fire. I don't know if that means you can't have a firepit or any kind of fire period. If it's the former, you could look at backpacking stoves. They're small and compact. Good way to boil some water.
a jar of peanut butter with granola and dried fruit and candy mixed in is a solid go to.
granola bars in general are solid, even the ones you make yourself.
fresh fruit like apples and bananas are good.
canned condensed soups are surprisingly good cold if you have access to fresh water to reconstitute them and you aren't worried about dehydration. that brings me to my next and much, much more important question:
do you have water figured out?
you can easily survive for four days without food, but you can't make it that long without water. you can't expect to rely on springs/streams/wells especially if you haven't been drinking from them for a while already.
you need about a gallon of water a day, more if youre exerting yourself, sick or eating very dry foods (like camping foods). so if you don't have a supply already figured out, focus on water. If you do have a supply already figured out, pack a gallon or so and some iodine anyway. you literally can't survive if for whatever reason the supply that was fine last time isn't running or is spoiled.
if you do end up having access to water, you can use flameless ration heaters to boil it quickly and use that to heat up any sealed foods you have. frhs' are powdered metals and salt that make a real hot reaction when you pour water on em. so if you had a bag with a frh in it, you had say some food that would taste good hot in another sealed bag, you could put your food bag in the frh bag and pour some water in, fold it closed, prop it up on a rock or something and wait for your food to get hot.
You can always go with a historic solution to packing long term food: Pemmican.

I dig what you're getting at here man, however my advice is just get a little propane camp stove. Mine has improved my camping life so greatly I'm kicking myself for not buying one before. It's not even expensive one and you can cook in no time flat anywhere. That being said Tuna and crackers is a classic, there is a lot more canned meat than tuna and you can get a lot of variety out of crackers.
Yeah, small propane burner and heating pot instantly makes camping a more enjoyable experience, because you have a wider variety of foods and drinks to choose from.
Heck Bobby, propane is the future!
Don't know how feasible this is to cook, but jerky will last more than 4 days. One of my favorite snacks, but it is very expensive.
Funny this comes up, I just made jerky at home for the first time a couple days ago. Much cheaper and very tasty. Easier than I was expecting too.
Did you just use a cut of meat from the store?
Yup, top round.
Would you mind sharing the recipe you used? I may have to try this!
The recipe I used ended up being terrible haha, so I kinda started winging it halfway through. The later batches turned out better after some adjustments but I'd still like a better starting recipe, so if you find a good one please let me know!
Yeah, beef jerky, even when making it yourself like @CloverSi@lemmy.comfysnug.space does, can be quite expensive depending on where you live. Thankfully beef jerky doesn't require high-end cuts of beef. Round Eye is one of the preferred cuts and even in regions with relatively high prices for beef (e.g. Germany) it's still quite economical compared to store-bought Jack Link's.
I have a friend that makes his own before trips. He has it down to x pounds of fresh meat per person per day. He just buys meat, adds seasoning, and dries/cooks it in his oven. There is surely a youtube on how to do it.
Beef jerky and salted/tinned fish.
Butter.
Eggs (unopened; only if not pasteurized/cleaned which you will not find in a typical US grocer for anyone other than OP).
Pretty much any baked goods.
Pasta (uncooked obviously).
Avocado, onion, tomato... Pretty much any fruit or veggie that isn't kept refrigerated at the store really.
Nuts.
Chocolate
Marshmallows
Graham crackers
Edit: NO FIRE?! The hell you camping?! Could you at least get some sterno or an electric camping stove? How you gonna have a camping trip without s'mores? 😩
Although I also would suggest a basic ass ice chest. My family went camping all the time for that length of time when I was growing up and we would bring regular food to cook over a portable electric stove and keep it in an ice chest. It would keep for at least 5 days.
You can usually tell by where the eggs are located in the grocery store. US eggs are 'cleaned' and kept in the fridge at the store (and at home), whereas a lot of other countries don't clean them and you just find them on a regular shelf instead of in the fridge.
It's interesting... It's mandated to wash eggs in the USA, whereas it's mandated to not wash eggs in Europe. Different standards.
Y'all have some big ol balls going backpacking with eggs.
Pickled or boiled eggs. I buy the 2 packs of already boiled eggs so there is never a partially opened container in my cooler.
Also carry quarts of eggs in cooler and cook all at once. Good with a bag of frozen hash browns. But this takes a way to cook (we carry Coleman style stove).
Some places have fire bans due to dry conditions and high likelihood of forest fires. Those don't include little stoves, though....
Another thing I don't see people talking about much is canned food. Almost all canned food is precooked or otherwise sterilized, and it takes years to expire when the can is left sealed. While cold ravioli isn't the most satisfying meal, it will fill your stomach without making you sick.
Exactly this. I have eaten cold ravioli in Yellowstone when we drove to the opposite end of the park.
We also have the tubes that keep a loaf of bread from getting crushed. Add a can of chicken and mayo packets for a rough but edible chicken salad sandwich.
Also sometimes carry the peanut butter and honey as both are shelf stable. Can even buy premixed.
First of all, depending on the area you're going to be camping in, is a camp stove out of the question? I don't know what's readily available to you in England, but there's quite a range of different options out there from little folding metal things that fit in your pocket that use solid fuel tablets up to briefcase sized ones that are basically like a regular kitchen stove that use 1lb propane tanks (or larger tanks with an adapter) and basically every form factor in between using just about any kind of fuel imaginable. You can even make a small stove out of some soda cans that burns denatured alcohol. You can probably have most of them delivered to you from Amazon before you leave for your trip, and assuming prices are similar in the UK to the US, there's options out there that will only cost you about £10-£20 plus a couple more bucks for fuel
Some of them are practically like cooking on a blowtorch so the flame is too concentrated and intense to do much besides boiling water, but even that opens up your cooking options a lot. Being able to heat up your food or make some coffee/tea/hot cocoa can be a huge quality of life improvement. And having a method to boil water to sterilize it in an emergency is always a good idea.
Usually, at least in the US, camp stoves are exempted from fire bans if that's what you're up against, look into your local laws about that.
Beyond that, your options depend a bit on how comfortable you are ignoring "refrigerate after opening" warnings on labels. A lot of things will say they should be refrigerated but would probably be fine for a few days as long as they're stored with a little care (container with a tight lid, wrapped up careful in some plastic wrap, foil, wax paper, etc. kept clean, dry, kept in a shady place out of the heat of the sun, etc) and depending on the type of camping you're doing, if you can bring a cooler full of ice you can bring just about anything you would normally keep in a fridge, some things can be kept cool by submersing them in a cool stream. Anything that's very sugary, salty, packed in brine or oil will probably last at least a day or two after opening. Many of those types of foods originated as ways to preserve stuff anyway.
But assuming you for whatever reason absolutely cannot have any type of cooking appliance and no access to any way to keep your food cool- Most fruits and veggies will last fine for a couple days unrefrigerated. Breads should be fine. Jams, and jellies, pickles, and other types of preserves are probably fine. A lot of smoked/dried/cured meats should be fine (jerky is a classic choice, salamis, summer sausage, etc. should also work but try to get a whole one, not pre-sliced, country ham if that's available across the pond would probably do the trick, maybe prosciutto) Dried fruits, nuts, harder cheeses. In general you can take a lot of inspiration from a charcuterie board. A lot of "just boil water" kinds of foods don't necessarilyneed the water to be boiled, it just makes it go a lot faster, you could do some overnight oats, instant noodles, etc.
As for your ideas, falafel and fritters are probably fine, but will depend on the exact ingredients and recipe you use. Calzones are probably fine, but I'd keep away from using too many wet ingredients in them, keep a separate jar/can of sauce to serve them with, don't load them up with too many veggies and such, stick to cheese and maybe cured meats like pepperoni for the filling. I had to look up pasties because we don't really have them in the US, but I'd say largely the same as the calzones, probably fine but be smart about what you put in them. At any rate, if you don't have a plan to keep them cool, I'd say you probably want to plan on eating them the first or second day, they might start getting a bit questionable after a couple days.
There's loads of hiking/camping shops here. Mountain Warehouse, Go Outdoors, Black's... OP has plenty of options if they want to pick up a stove.
Yeah, I figured they have options, I'm just not sure exactly what they are with different countries having different regulations and standards, like I kind of suspect that 1lb propane tanks may not be as common in areas that use the metric system, and I don't know what the closest equivalent would be if there is one, though I suppose if anywhere is going to measure propane in pounds outside of North America it would probably be the UK. I could also see some places banning or restricting things like white gas or esbit tablets for one reason or another, and of course different countries having different terms for things.
You've gotten tons of good suggestions, but also like just bring a camp stove? Even if an actual camp stove isn't allowed, you could easily use a tea candle. It takes a bit longer but it will boil water.
There are some amazingly small and light stoves out there. There's the Esbit stove (size of a deck of cards, including fuel) and the PocketRocket (fits in a mug but needs bulky fuel). Then if you're willing to deal with collecting firewood, there is a whole family of wood burning stoves that can produce a surprisingly strong fire as long as there is firewood in the area. They then pack down completely flat.
24 packs of Scampi Fries and a dozen Mars Bars.
You can have meat, but something cured and in a pack like biltong.
And every hiker's favourite, Kendal mint cake, which is as close to Terry Pratchett's dwarf bread as any substance I know.
And this is England. Chances are you'll be like two miles from the nearest shop at a push.
I tried to look for a super-remote forest location last year; my intention was to take a tent, get dropped off on the edge, go deep into a forest with laptop & keyboard, to write some forest-inspired music. I was pretty shocked to find out that all our once-deep forests are criss crossed with roads. You were kinda joking, but you're literally right, there's nowhere far from a road in any of our forests.
Found the South African!
No but I'm a fan of the accent. Or at least Joss Ackland's in Lethal Weapon 2. Diplomatic immunity!
They started selling it in the UK a few years back. It's quite expensive though.
I'm going to guess Lake District or Scotland. You can easily be several hours walk from shops.
Well, Scotland isn't part of England. But sure, you can get far from civilisation, by UK standards. Dartmoor and Yorkshire Moors are others. It's only a few miles as the crow flies, but it'll feel a lot more than that when carrying a load of camping stuff and having to go around a river.
Is there a reason you can't use a Coleman style camp stove or single burner backpacking stove? Those are standard fair for campgrounds and backcountry.
Fare*
Although, certain fairs have also been known to be near-standard fare at campgrounds, here and there.
Jet Boil’s are compact and awesome.
Jet boils are not compact. They are awesome, just not great if you are a gram counter. Probably exactly what this guy would want though as it sounds like he is car camping.
I’ll add cured sausages such as chorizo and dried tomatoes. Both keep well unrefrigerated and add a lot of flavor to any dish.
Lots of good answers here.
Another option would be taking MRE-s (meal ready to eat) it's pre-packaged food designed for soldiers to eat while not having access to a kitchen. It usually has a solution to heat the food and plenty of calories for a full day.
You can order them on the Internet from military surplus or other places and there is a bunch of flavours to choose from. They also have a long shelf life, don't need refrigeration, and fit in a small space.
Are they not famously gross...?
They scale on actually bad to like, upscale cafeteria food. It really depends on what you get.

Nice!
jerky, granola, lots of vegetables are fairly stable and can be eaten raw. Carrots, garden peas, green beans, lettuce (you can eat that in the first day or two before it wilts), apples,
Most of the foods that existed before the refrigerator was invented!
Pemmican
Beef jerky
Pork rinds
Apples and other fruits
Nuts
Remember to bring water.
Can you bring a canister cook stove? something like a Jetboil? that way no need for a whole fire etc. you can boil water etc, cook basic stuff like ramen etc. make coffee...Hardy veggies should be good, beef jerky, cured meats like salami etc. dried fruits and nuts, bread, crackers etc. regular fruit, granola bars...i would just bring a little burner thing if you can it will be so much nicer than only eating cold foods etc.
You can easily make overnight oats with dry ingredients (oats, fruit, nuts/seeds, some syrup) and some water each evening and then have them for breakfast/lunch.
It depends if you’re not trying to poop that whole time?
I'm not sure how we're supposed to help OP without knowing his target poop rate. Babybel cheese and canned Hormel corned beef hash are going to produce wildly different results, for example.
We need to know the Poop:Day ratio
Tabouleh is great in summer and does not need to be cooked.
You put some bulgur wheat, chopped tomatoes, chopped cucumbers, fresh herbs like parsley or mint if you have any with a bit of olive oil and lime in a container. A bit of water and you let it like that for at least half an hour. I usually prepare it in the morning for lunch when I go hiking.
My partner makes very nice Tabouleh, you can have it alongside pretty much anything.
How come most people try to solve the no heat problem instead of the food that does not need heating problem?
Some stuff that can taste well even "cold":
Canned tuna + precooked canned beans + onion + salt pepper oil vinegar.
Watermelon (quite inefficient when it comes to nutritiom but tasty)
Bread + mustard+ hard cheese or certain types of sausages (especially smoked with low amount of water inside).
Most vegetables and fruit will survive 5 days if they do not have defects and you can keep insects away from it.
Because getting a cheap ass stove is so much easier and opens a shitton of options.
Because a Trangia alcohol stove solves the no heat problem and opens up more options.
For some reason I always forget about the hard cheese, but it makes eating this way so much more doable for some reason
MREs might be a good choice - I know the US ones come with a water-activated device to heat your food up. They're also about 1250 calories each and balanced for recovering after intense exercise.
I only know the German ones and while they'll keep you alive and healthy easily, they won't keep you happy.
(Edit: but my knowledge about those is old, maybe they're delicious and wonderful by now, but I doubt it)
I went through the whole menu not too long ago and they can be pretty hit or miss, but very edible. They've removed some of the worst offenders like the "vomelet". Most things taste uninspired but the meals can be pretty diverse and there's some solid options like chili mac or maple patty. None of them have made me particularly unhappy. I hear German rations are really good though, so maybe I just have low standards because we have worse food here.
I'm not speaking from personal experience, but according to some family members in the U.S. military they still suck here, at least in terms of flavor.
Bonus point, you won't poop while you're eating MREs. Those things bind you up something fierce.
Meal Refusing to Exit.
This guy gets it ^
Boiled eggs and boiled potatoes. They will surely last 3 days.
Boiled potatoes, maybe. But I wouldn't count on the eggs, especially when it can get hot outside.
According to this survivalist book I've got they should be fine. It recommendeds eating them in a box with a fox, or in a boat with a goat.
What if you don't like them?
Then you will be politely, yet firmly, asked to leave.
My mother's fridge is only maintaining a temp of 6C (you want 4). While waiting for a new fridge she was concerned about this. I explained that for the first 15-20 years of her life, their was kept cold by putting in a cabinet with a block of ice in it. She calmed down a lot about it after that. :)
I’d recommend cured meats like smoked sausage or jerky along with crackers. I believe you can do cous cous without boiling the water too but I could be wrong there.
There are also some dehydrated backpacking meals that don’t require boiling the water. Usually they are the breakfast ones with powdered milk and granola and dehydrated fruits - they’re delicious and some of my favorite backpacking food!!
Get some mason jars and do oldschool canning. Food will stay preserved well as there's no bacteria at the temperature you put it in there, and no air will get in.
Toss in some macaroni and pasta sauce, goulash, tomato soup, premade cup-o-noodles with your favourite veg and protein. Your imagination is the limit.
I mean I would just eat cold canned ravioli because that's delicious and it would be a great excuse to eat cold canned ravioli, but you do you
Freeze-dried vacuum-packaged hiking food. A bit expensive though.
Get bread and canned fish. You can also get canned tomato soup and eat it cold. And then make sure to bring some fruits or something.
Whenever I go camping I pack a cooler with ice and put my perishable food items in there. Easy to grab snacks, like fruit, pastries, and pre packaged items are also a favourite of mine.
Also, having a portable grill helps when you cannot use fire to cook.
When I go camping, I do almost all my cooking on a little alcohol stove, they don't take special fuel, any gas station will have the yellow Heet that you can use for fuel in it.
But what I usually eat:
This is great info! Does the "heet" stove give any flavor to the stuff you are cooking?
None. You don't want to be roasting a marshmallow or hot dog next to the open flame, but cook with pots and pans over it.
Also, you don't have to use methanol, here is a good article that I found that compares some of the fuels you can use in it.
Some boiled eggs are easy
There is no way I would be comfortable eating a 4 day old, unrefrigerated boiled egg... or want to be in the vicinity of a person scarfing down 4 day old unrefrigerated boiled eggs.
Whats the problem? Even fresh, unboiled eggs are good for more than two weeks unrefrigerated.
Maybe the problem is just conceptual for me, I may just be easily off put.
You wash the wax film away and crack the shell if you boil them. They will spoil fast if you do not seal the egg - like the preboiled coloured "easter" eggs.
You don't wash anything away and why would you crack the shell? Just boil the egg. It's good for about two weeks at room temperature according to every source I can find. Thats also what it says on the preboiled Easter eggs.
No easy access to fire? Is that because fire is forbidden or because getting wood and/or a place to burn stuff isn't available? If it's the latter, a gas burner is your friend
Babybel cheese
Don't pussyfoot around, you know you need the full size wheel of Edam.
What I found to be quite interresting and working well are the solid fuel stoves from esbit. You should be able to bring them on a flight and one small tablet lasts long enough to boil enough water for some instant ramen, soup or a cup of instant coffee.
If you're in England look into the Duke of Edinburgh club. It's an outdoors camping club for youth. You should be able to find a packing list and it will have food suggestions.
Fruits, rice, pasta
Edit: dont do rice, it’s a bad idea
Cooked rice won't last 3 days?
Hmmm, you’re right, sounds like I overestimated rice… Let me edit before I kill someone with my ‘advice’.
I don't know about pasta, but cooked rice can go bad within a few hours, definitely wouldn't eat it after a few days. Unless you mean dried rice but I don't know how you'd cook it without boiling water.
Haven't tried rice, but buckwheat you can toss into cold water, let it soak overnight and have a meal ready by the morning. An old time-poor (and money-poor) student's trick.
Huh, never heard of that, good to know! Though I've actually had a hard time finding buckwheat (and most grains besides wheat, really) at a reasonable price; the only options at my closest grocery store are all extremely marked up organic options in tiny containers. It's too bad, I really like whole grains.
Yup, rice and pasta.
Not fruits tough, unless they r dehydrated.
Fruit can last more than a few days without being dried though.
It depends on the fruit. Look at a banana funny and it'll go rotten. Apples are pretty stable.
True, though for a four day trip, as long as you get it at the right ripeness I don't think any fruit would go bad in that time.
But yeah apples are a great choice, like you said they're good basically forever but also pretty easy to pack - not as easy to bruise as other fruits. Oranges also come to mind as a good travelling fruit.
You can get either canned or dried fruits and veggies that last longer un-refrigerated and have some nutrition to them. Obviously there's power bars as well. Dry cereal if you don't mind eating it dry, makes a decent snack too, or bring powdered milk if you do want to eat it with milk. I've heard freeze dried foods are popular with backpackers. Bananas last long enough if you get them fresh enough. I think there are other fruits and veggies that you don't need to refrigerate for them to last long enough, like tomatoes, cucumbers, oranges, pears, kiwis, apples, etc, just as long as you eat the whole thing in one go cause they don't last as long once they're cut or bit into. Oh and fruit cups are also an option. And of course there's bread, but if you want some variety there you can make/buy some banana bread to take with you as well. Popcorn also lasts quite a while if kept in a sealed bag. You can also eat ichidan or other dry packaged noodles dry, just break them up into smaller pieces in the bag, take out the flavour packet, and either pour the packet into the bag, or pour the noodles and flavouring into a bowl, and mix it up. Tastes pretty good, and makes for a good snack. Not very nutritious, but cheap and easy. There's also pop tarts, which can be eaten cold.
Those are the ones I can think of off the top of my head. You don't need to take all of them for just 4 days, but it's nice to have options.
That's just long enough for things that aren't shelf stable to start going bad, depending on local conditions. Bread can mold in a couple days though, in warm and humid places.
So, focus in on shelf-stable or preserved things, whether made in a modern method, (sterile packaging of some sort) or an old fashioned method, (drying, curing, smoking) or just naturally able to keep (nuts, seeds, chocolate, honey).
Someone posted their granola bar recipe, that looked pretty solid. I would certainly not bring a bunch of pasties or a calzone unless I was also bringing a cooler. Then I'd be bringing ingredients and tools and making them on-site just for fun, as I assume I'm now car camping, or at least camping fairly close to my vehicle. If backpacking in, then absolutely not. Ready-to-eat, shelf-stable stuff only, to cut weight and stay efficient. And a pasty or calzone would squish in the backpack and end up gross anyway.
Triscuits.
Lembas bread
Can you share that recipe, Legolas?
This website is very helpful and informative https://trailcooking.com/
Ramen and soylent
Protein bars & Nuts. Lightweight, packed with nutrients / calories.
Canned food tends to be heavy for the amount of nutrients included.
MREs are great too, lots of variety. But, these things can plug you up pretty bad. The uh, gum, will help flush you out. Pretty bulky though.
I highly recommend getting a gas burner, if you are comfortable with it. It’s great for cooking while camping. We’ve recently made tacos and risotto while camping. Also, depending on the brand/model, it works in most weather and you’re not reliant on gathering wood for a fire.
Why no boiled water? A small backpacking stove, something like a Pocket Rocket from MSR, is lightweight and can give you a very small, controlled flame that's hot enough to boil a liter of water in less than two minutes. And if you look around on Amazon, you can find them even cheaper than MSR, usually for less than $20. They connect to an isopropane canister which runs about $5.
Hardtack
Remember to knock it against your mug of grog to get the weevils out before you soak it in there.
Beans
Can’t you just bring a Trangia stove? They burn for EVER on half a litre of spirit.
If you bring a few apples and don't bruise them on the way in, they'll keep several days and give you some nutrition.
Here's a list of some candidate foods, compiled from the experience of people who live in vans and other vehicles without refrigeration.
Nuts and dried fruit, granola bars, halva, canned beans in tomato sauce, canned meat and fish and other canned stuff, bread, all sorts of cheese, cucumbers, smoked meat were the staples of no-cooking-needed foodstuffs that keep for several days in the summer when I did hiking in my younger days. For breakfast, muesli with milk from powder. You can prep buckwheat overnight in cold water and eat it for lunch or breakfast. Onions and garlic to add taste, fresh herbs will keep just fine, too. Sun-dried tomatoes. Bell peppers.
Basically, you need to start thinking antique: what did travellers and adventurers eat several hundred years ago when refridgeration wasn't a thing?
You can dehydrate literally anything, and re-hydrate it on the trail with a little water and heat. Meats, Fruits, Vegetables, Soups, the works.
Tortillas
Mcdonalds cheeseburgers. I saw a video of a guy doing the pacific trail with just a bag of hamburgers and he said they lasted well over a month. He also said its the best thing hes ever done as they gave him more strength than protein bars ever have. If i find it ill post.
Edit:I couldnt find the hamburger but i found mcdouble guy. I think 90 miles is still a few days worth.
Eating a month old burger sounds like a great way to get food poisoning
Does it count as food poisoning if it's not technically food?
