Hawaiian Chicken Kebabs

1. In a medium bowl, whisk together the ketchup, brown sugar, soy sauce, and pineapple juice to make a sweet and tangy marinade.
2. Cut the chicken, bell peppers, and onions into bite-sized pieces so they grill evenly.
3. Add the chicken and vegetables to the bowl with the marinade. Make sure everything is well coated, then let it marinate for at least 30 minutes to soak up those amazing flavors.
4. Once marinated, thread the chicken, bell peppers, onions, and pineapple chunks onto the skewers, alternating for a cheerful, colorful look.
5. Preheat your grill to medium-high heat. Place the skewers on the grill and cook for 10 to 15 minutes, turning them occasionally so everything cooks evenly and gets just a bit of char.
6. Serve these kebabs hot off the grill and savor that taste of sunshine!
