This recipe for sweet potato and harissa stew. I know you’ll appreciate a filling, comforting bowl of spiced sweet potatoes and greens along with a little nut butter for some vegan protein! I prefer to use almond butter but peanut butter would be more traditional and work equally well. Harissa is a red pepper paste that can be found in the International section of the grocery store. It can be spicy, but also comes in mild versions, and it a great flavor booster.
