@thor Try wild emmer if you can find it. It should be cheap, but it's very nutritious. It's also richest in proteins compared to other… let's call them cereals. Potatoes are just sugars — you do get your calories, but I have a problem feeling "full" eating only potatoes, you just get feel hungry again in an hour. Emmer might be a little hard to digest to some, but if it suits you, you're in luck — it's hands down the best side dish I could find.
