This variation of Hong Kong-style sweet and sour chicken adds a tropical twist by incorporating pineapple into the dish. The combination of juicy pineapple chunks, tender chicken, and the tangy sweet sauce creates a delightful flavor profile. The chicken is marinated, fried until crispy, and then stir-fried with bell peppers, onions, and pineapple. The sauce, made with vinegar, ketchup, sugar, and soy sauce, is poured over the chicken and vegetables, resulting in a colorful and appetizing dish. Enjoy this sweet and sour chicken with pineapple over steamed rice for a taste of Hong Kong at home.
