amys has chilli, eden foods does canned rice and beans/lentils, you can buy microwaveable rice in little pouches and chuck canned sweetcorn, beans, etc in there too. crackers and a spread/pate/peanut butter fill a gap pretty well, as does instant oatmeal. we have a lot of foil packed shelf stable indian stuff here- but if you've not got a big indian population where you live, then you probably don't. instant noodles are pretty decent with a peanutty sauce on them, or cooked with a stock cube- specially if you add beans or veggies. you can even buy canned stirfry veggies although they're not exactly awesome. oh yeah- baked potato with baked beans on it is a student stable where i'm from, which can definately be done in a microwave (do the beans seperately, they'd explode way before a potato cooks!).
