I like peanut butter a lot. It's a good source of protein and carbohydrates, it keeps for a long-ish time, and most people have no problems
stomaching it, even day after day. Most of us have fond memories of peanut butter sandwiches from when we were kids, and as long as you don't keel
over and die from an allergy, you're good to go.
I also like tuna packed in oil. It keeps as long as any MRE, tastes better, and while not quite as good for you, it is more familiar. Only downside
- no mayo.
The upside? Works pretty well with mustard, which will store a helluva long time and makes a lot of other foods more palatable.
Foods like..hardtack and tinned ham. 4 cups flour, 1 cup water, 4-6 tsp salt, mashed together and cut into squares, poke some holes in, bake at 375
for 25-30 minutes per side, and there you have it. Other folks do it differently, but it's not going to taste great after 6 months no matter what
you put in it, so I don't think it matters much.
I like mine with ham or jam, depending upon the position of the sun in the sky, and how hungry I am.
Don't get me wrong, I love jerky and dried fruit, but they don't hang around long, I eat them too rapidly. If I could keep a store of jerky, I
would. But it's just too tasty for its own good.
I also like rice and beans. Rice is poor in terms of nutrients, compared to other foods, but it's not terrible, and it keeps pretty well. It's
also easy to prepare, doesn't require a ton of water, and it fills your stomach up (even if it's not really a full meal's worth of nutrients, it
gives you energy and staves off hunger).
Hard candies and water additives (hot chocolate, tang, etc.) also shouldn't be overlooked.
I'm still undecided on vitamin supplements. They don't keep well, and that's no good. Of course you need them, but a balanced diet should provide
you everything you need, and the body is pretty good at weathering deficiencies.
I'm interested in learning more about the shelf life of dried seaweed. Theoretically it keeps for a couple of years, comparable to canned veggies,
and it's very good for you. I've never actually eaten 2 year old seaweed though, so I have no idea if its palatable.
Canned water chestnuts are quite good, also pickled peppers, applesauce, jars of pineapple (not cans), and mushrooms. If you have the space, I think
these are better investments than a bunch of multivitamins. I could be way off-base, so please correct me if I'm wrong.
