Okay, after reading some, I think my gut instinct was spot on. Beans are going to be the staple, and some rice as well. There is a great post in here about how to cook beans to remove a lot of the stuff that makes them objectionable in a diet:
There is a book called Thrive Foods that has some suggestions, though he is actually all about raw vegan. However I think the food suggestions hold.
Missing from that list is sweet potatoes and I think you should keep those in the diet. Also avocados. If you have an Aldi nearby I think their avocados are typically $1 per.
Really, I think you're looking at shopping in bulk. Beans in bulk, rice in bulk, nuts and seeds in bulk. It's Farmer's Market season and sometimes you can get good deals on produce at the Farmer's Market, so try checking those out too. Stalk sales. Buy whatever is on sale. USE whatever you buy. Don't waste food. That's the big thing... a lot of people get produce and then don't even eat it so it goes bad and they have to throw it out. If you have money to just throw in the trash please send it to me instead, I could use it! So whatever you buy, use. Don't overbuy unless you're planning on freezing it.
More blogs that might be helpful for ideas of what to eat:
I hope that helps some. It's tough when you're on a tight budget. I would say on the weeks you have a bit extra, buy something in bulk or something you can freeze so you can stockpile it away for later. I have about one week every few months where I spend $40 buying a bunch of bulk stuff, but it lasts a few months too, so it's not that bad. Doesn't make that particular grocery store visit any more pleasant though LOL.
$20 a week is about what I spend normally. But I do eat dairy (cheese!) and meat. Most of that goes to meat. If I had to sustain without meat, I think I'd go back to eating more rice for sure.
