Preheat your grill to medium-high heat.
In a small bowl, whisk together the soy sauce, brown sugar, ketchup, rice vinegar, garlic powder, onion powder, paprika, and salt.
Thread the chicken, bell peppers, onion, and pineapple chunks onto the skewers, alternating between the ingredients.
Brush the kabobs with the sauce and let them marinate for 10 to 15 minutes.
Place the kabobs on the grill and cook for 8 to 10 minutes, turning occasionally, until the chicken is cooked through and the vegetables are slightly charred
Serve hot and enjoy your delicious Hawaiian Chicken Kabobs.
