So, I don't know if you know this, but I'm poor.
It could be worse, of course. I am not living out of a cardboard box or eating Raman three meals a day. I am, however, learning to budget very carefully and eat very cheaply.
I think a big part of eating cheaply is to make the most of what you already have in your cupboard. Here's my list, a lot of which is left over from things I bought to make Thanksgiving dinner:
1/2 pound cheddar cheese
1 cup pecans
1/2 loaf homemade wheat bread (yum)
2/3 pound masa
2.5 sleeves saltines
2/3 bag frozen California blend vegetables
1 bag frozen brussel sprouts
2.5 cups homemade turkey stock
From this list, I will eat for 14 meals. To supplement this list (and therefore eat 3 meals a day for a week), I'm going to purchase the following:
tomato (probably canned, but it depends on how cheap the fresh ones are)
This week is going to be kind of a Mexican-themed week, what with the masa, rice, and beans. It's also going to be a "do creative things with frozen vegetables" week. The plan is to post the best stuff I come up with. This should be exciting...
