Eggs require you knowing someone who raises chickens. Store bought eggs can't be left at room temp, but unwashed fresh eggs last weeks at room temp. Usually cost $3 a dozen. I live in a major city and can find them.

Sharp cheeses don't require to be kept cold.

Vegetables obviously are perfectly fine at ambient temp.

I get the weirdest looks when all my campmates are eating lousy hot dogs and I'm having taco night with mexican rice and refried beans for dinner. Pancakes and bacon is my go-to breakfast as it's good and filling for a long day of adventures. All you need is "just add water" pancake mix.

I'm going camping this weekend I actually need to start meal planning.

Check out the Bear Creek line of dried soups to copycat. They taste great, so they put some research into things that work. Also check out Amazon for things like cheese powder, etc. that are hard to make at home. I can personally recommend Peak milk powder, got it for camping and continued it for use as creamer at home, it's honestly delicious.

Have you tried just plain powdered milk? (avoiding the non-fat variety)

I make it all the time with Peak on the trail or at home. I don't drink milk so I never have any in the fridge. Can't tell the difference.
