Specifically looking for recipes that are relatively cheap, filling, and aren’t too time-consuming so I can keep up a routine without getting burned out. I have a 10 cup rice cooker so rice combined with other things would be pretty easy. I have a Costco membership and there’s a restaurant supply store near me, as well.
I’d look into плов and the general pattern of adding rice with ingredients to a rice cooker with some sauce and then mixing it all together when its done cooking.
Bumping this comment because plov. Carrots are cheap, cabbage is cheap, onion is cheap, rice is cheap, you can add beans for protein for cheap, and the end result will be flavourful and good.
