01 - In a large mixing bowl, whisk together the soy sauce, honey, olive oil, lime juice, minced garlic, and black pepper until well combined.
02 - Add the chicken cubes to the marinade and toss to coat evenly. Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration.
03 - If using wooden skewers, submerge them in water for at least 30 minutes to prevent burning on the grill.
04 - Thread the marinated chicken, pineapple chunks, bell pepper pieces, and onion wedges alternately onto the skewers, distributing the ingredients evenly.
05 - Preheat an outdoor grill or grill pan to medium-high heat, approximately 375°F to 400°F.
06 - Place the kabobs on the grill and cook for 12 to 15 minutes, turning occasionally with tongs, until the chicken is cooked through to an internal temperature of 165°F and lightly charred, and the pineapple is caramelized.
07 - Remove the kabobs from the grill and garnish with freshly chopped cilantro or parsley if desired. Serve immediately.
