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, toss to coat evenly. Cover and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration.
03 - Soak wooden skewers in water for 30 minutes to prevent burning during grilling.
04 - Thread marinated chicken, pineapple, bell pepper, and red onion alternately onto skewers, leaving small gaps between pieces for even heat distribution.
05 - Preheat grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
06 - Grill skewers for 12 to 15 minutes, turning every 3 to 4 minutes and basting with remaining marinade, until chicken reaches internal temperature of 165°F and develops a nice char.
07 - Transfer skewers to a serving platter, sprinkle with chopped cilantro and accompany with fresh lime wedges.
