01 - In a large bowl, whisk together olive oil, soy sauce, honey, minced garlic, lime juice, smoked paprika, black pepper, and salt until well combined.
02 - Add the chicken cubes to the marinade and toss to coat evenly. Cover the bowl and refrigerate for at least 15 minutes, or up to 2 hours for deeper flavor penetration.
03 - Preheat your grill to medium-high heat (approximately 400°F). Brush the grates with oil to prevent sticking.
04 - Thread the marinated chicken, zucchini slices, pineapple chunks, bell pepper pieces, and red onion wedges onto skewers, alternating ingredients for even cooking and visual appeal.
05 - Place the skewers on the grill and cook for 10 to 12 minutes, turning every few minutes, until the chicken is cooked through (internal temperature of 165°F) and the vegetables are tender with lightly charred edges.
06 - Transfer the grilled kabobs to a serving platter and garnish with fresh cilantro or parsley if desired. Serve immediately.
