A friend and I watched Hormel factory footage (Rifftrax lol) CW https://www.youtube.com/watch?v=EagPzmaVc38
They and I were sickened and discomforted by the footage up until the moment the meat was being sliced into bacon strips and all of a sudden he's like "oh, that's the yummy stuff!"
Literally any whole grain paired with literally any legume. The combination gives you every essential amino acid in protein. Popcorn and baked beans is a meat replacement.
