Also leguming hard, but split pea and condiment soup is one of my go-to almost instant meals. I just put about a half pound of peas in my (important!) InstaPot along with some jam, mustard, spices, oil, boullion, and leftover tomato sauce if I have some. Currently, I have a bunch of prepared mirepoix in my freezer than I sautee first, but it isn't the main part. Sometimes I thicken it with flour or add whatever veggies are about to go bad. It make about 4 decent portions, and scales very well!
