Chilli Chicken Tacos are a fusion dish that combines the flavors of Chinese-style chilli chicken with Mexican-style tacos. The chicken is marinated in a spicy sauce and then stir-fried with onions, bell peppers, and spices. The mixture is then served in taco shells and topped with lettuce, tomatoes, cheese, and salsa. The result is a delicious and spicy taco that is perfect for a quick and easy meal.
