01 - Whisk together olive oil, BBQ sauce, soy sauce, honey, garlic, smoked paprika, salt, and pepper in a large bowl until fully combined.
02 - Add chicken cubes to the marinade and toss to coat evenly. Cover and refrigerate for at least 30 minutes, up to 2 hours for deeper flavor penetration.
03 - Soak wooden skewers in water for 30 minutes to prevent burning during grilling.
04 - Thread chicken, pineapple, bell pepper, and red onion alternately onto skewers, leaving small gaps between pieces for even heat circulation.
05 - Preheat grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
06 - Grill for 12–15 minutes, turning every 3–4 minutes and basting with remaining marinade, until chicken reaches internal temperature of 165°F and develops char marks.
07 - Transfer skewers to serving platter, garnish with chopped cilantro, and accompany with lime wedges.
