That is not what I think of when I think chop suey.
@PTree15 describes it on another thread I guess. I honestly think of canned LaChoy veggies, more bean sprouts, cooked cabbage and a brown corn starch based sauce. I over rice or chow mein noodles
I made cabbage, onions in Instant Pot, and soy curls onions and red pepper -soy curls doused with Lamb seasoning from Penzeys, cumin spearmint, other stuff, their Revelotion, which is like a seasoned salt and crushed pepper, and together added some soy yogurt that I strained and added mint and tzaziki. Quite tasty!
