01 - In a large bowl, whisk together olive oil, BBQ sauce, soy sauce, honey, garlic, smoked paprika, salt, and pepper 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 while grilling.
04 - Thread chicken, pineapple, bell pepper, and red onion alternately onto skewers, leaving a little 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 the chicken is cooked through and has a nice char.
07 - Transfer to a platter, garnish with chopped cilantro and serve with lime wedges.
