Holy cow- I asked a question and went to bed. When I woke up it was like Santa had brought a whole book of suggestions. Thanks!

FWIW, I know that MREs/Morehouse stuff exactly fits what I asked about- I should have added that I`m not willing to pay that much. Also, It was one of those websites on freezerbag cooking that planted the alcohol stove idea in my mind. I plan to try some in the futre, but for now I`m just looking for single ingredient kinds of stuff. My stove isn`t a Trangia- it`s a super basic homebrew that does a great job of boiling water (at home with nice weather and no wind). I have no simmer provision on this model and still have some doubts as to how well it`ll work in less than perfect conditions.

Lentils- I love lentils, but when we cook them at home we always boil them for ten minutes or so- Are there instant varieties, or by presoaking or something, do they cook without simmering?
Couscous and polenta- never tried these, but I`ll get some today and see if I like them.
Other suggestions noted but I don`t have questions about them, thank you very much.
