These Shanghai-style chicken lettuce wraps are a light and flavorful dish that can be made using a food processor. The chicken is minced in the food processor along with water chestnuts, mushrooms, and green onions. The mixture is then cooked in a sauce made with soy sauce, hoisin sauce, and ginger. Serve the chicken mixture in lettuce leaves and garnish with chopped peanuts and cilantro for a healthy and delicious appetizer or main course.
