Sweet Potato-Peanut Bisque 67 This satisfying vegetarian, sweet potato soup is inspired by the flavors of West African peanut soup. We like the added zip of hot green chiles, but they can sometimes be very spicy. It's best to take a small bite first and add them to taste. Try chopped peanuts and scallions for a different garnish. Serve with a mixed green salad with vinaigrette. Recipe by Nancy Baggett for EatingWell.
