01 - Whisk together olive oil, BBQ sauce, soy sauce, honey, garlic, smoked paprika, salt, and pepper in a large bowl until well 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.
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 a small space between each piece for even cooking.
05 - Preheat a 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 extra marinade, until chicken is cooked through and nicely charred.
07 - Transfer skewers to a platter, garnish with chopped cilantro, and serve with lime wedges on the side.
