These Hunan-style chicken lettuce wraps are a delicious and healthy option for a light meal or appetizer. Using a food processor, you can finely chop the chicken, water chestnuts, and mushrooms, which will give the filling a nice texture. The filling is then stir-fried with a spicy sauce made with chili peppers, garlic, and soy sauce. To serve, spoon the chicken filling onto lettuce leaves and garnish with chopped green onions and cilantro. The crisp lettuce provides a refreshing contrast to the flavorful and spicy chicken filling. These Hunan-style chicken lettuce wraps are perfect for a quick and easy meal or as a party appetizer.
