01 - In a large bowl, whisk together BBQ sauce, olive oil, soy sauce, garlic, smoked paprika, black pepper, and salt to create the marinade.
02 - Add chicken cubes to the marinade, toss to coat thoroughly, cover, and refrigerate for at least 30 minutes, up to 2 hours for maximum flavor absorption.
03 - Soak wooden skewers in water for at least 20 minutes to prevent burning during grilling.
04 - Preheat grill to medium-high heat (400°F) or prepare a grill pan on the stovetop.
05 - Thread marinated chicken, pineapple chunks, bell pepper, and onion alternately onto the skewers, ending with a piece of chicken or pineapple to secure the arrangement.
06 - Grill skewers for 12-15 minutes, turning frequently and basting with extra BBQ sauce halfway through, until chicken is fully cooked and lightly charred.
07 - Remove from grill and garnish with chopped cilantro or parsley. Serve immediately with lime wedges on the side.
