Unfortunately I am currently too crippled to be able to handle more intensive/time consuming meal prep, but yes absolutely for most people, it probably makes more sense to start from raw beans.

Also shout out to peanut butter.

....real peanut butter, that isn't mostly sugar.

Very good source of protein and... I think also complex carbs?

Also also: Maybe consider a basic resealable cannery set of jars, so that you can store things a while, works for storing way more than just preserving jam or what not, you can use em as cups, ain't made of plastic but they can be used as just verticaly oriented tupperware.
