I can get many varieties of squash and brassica cultivars locally for a ridiculously low price as most of the entire county I live in used to be all farmland and we have a ton of actual farmers markets that aren't fully commercialized

So I eat a lot of acorn and spaghetti squash, broccoli and cabbage in many forms, peppers are usually cheap as well as carrots. Onions are cheap as well as bananas

Beef and chicken bouillon for cheap flavor, whatever fruit is on sale for desert

Tofu for protein as I can't stand the texture of beans
