Grilled Sweet and Sour Chicken Skewers are a healthy and flavorful option for a summer barbecue or a quick weeknight dinner. This recipe features marinated chicken breast pieces threaded onto skewers with colorful bell peppers, onions, and pineapple chunks. The marinade is made with a combination of soy sauce, honey, vinegar, and garlic, which adds a sweet and tangy flavor to the chicken. The skewers are then grilled until the chicken is cooked through and slightly charred, creating a delicious smoky flavor. Serve these skewers with a side of steamed rice or a fresh salad for a complete and satisfying meal.
