Making BBQ Pineapple Chicken Kabobs is straightforward if you follow these steps:

1. Marinate the Chicken: In a bowl, combine diced chicken with ½ cup of BBQ sauce, olive oil, salt, and pepper. Mix well, cover, and marinate for at least 30 minutes in the refrigerator.
2. Prepare the Skewers: If using wooden skewers, soak them in water for about 15-20 minutes to prevent burning.
3. Preheat the Grill: While the chicken marinates, preheat your grill to medium-high heat.
4. Assemble the Kabobs: Thread the marinated chicken, pineapple chunks, bell pepper pieces, and onion wedges onto the skewers, alternating as you go to create a colorful presentation.
5. Grill the Kabobs: Place the skewers on the preheated grill. Cook for about 15-20 minutes, turning occasionally, until the chicken is cooked through and has beautiful grill marks.
6. Glaze with BBQ Sauce: During the last few minutes of grilling, brush additional BBQ sauce over the kabobs for an extra layer of flavor.
7. Check for Doneness: Ensure that the chicken reaches an internal temperature of 165°F (75°C) using a meat thermometer.
8. Remove from Grill: Once cooked, remove the kabobs from the grill and let them rest for a few minutes.
9. Garnish: If desired, sprinkle fresh cilantro over the kabobs for a pop of color and flavor.
