Harissa is a Moroccan hot sauce made with chili peppers, garlic, olive oil, and spices. It gives this stew a slow heat, making it the perfect dinner for a chilly fall evening.
Different brands of harissa can vary a lot in spice level. You might want to start out with a teaspoon or less and add more to taste.
