Yes, but you have to have access to a supermarket for that to work and buy in (relative) bulk. A lot of the poor only have access to convenience stores and mini marts which makes the equation quite different. The cheapest way to cook would be to buy whatever meats on special, a bag of frozen vegetables, some rice, and some sort of sauce, it won't be particularly nice but it would be fairly nutritious and only cost a few dollars.
