Adapted from Groundnut Stew in Sundays at Moosewood Restaurant. PB2 makes this stew creamy and rich for a fraction of the calories, although you can sub regular peanut, almond, or cashew butter if you prefer. Stir in white beans or tofu to bump up the protein even more. Serve with cooked millet or cornbread for a hearty meal that omnivores and vegans alike will love!
