I like making pots of rice and beans. It's really cheap and you can add just about anything. A pot should last a few days and supply good nutrition. I like to start with a good rice, add some veggies, a fat source, and a salt source. Fish sauce is nice. Cheese works well. Crack an egg or two for variety. If you use canned beans, rinse them well and add at the end. Water should be 2.5 the volume of the rice. You get one pot for several days of food and don't even need dishes. No need for anything but a $0.33 can of beans and part of a $2 box of rice and a pan. It is a bit extreme, but I lived on $12/week when I started my company and just ate beans and rice.
