01 - In a large mixing bowl, combine olive oil, soy sauce, honey, minced garlic, smoked paprika, black pepper, and salt. Add chicken cubes and toss thoroughly to coat. Cover and marinate for at least 15 minutes, or refrigerate for up to 2 hours for enhanced flavor.
02 - Preheat grill to medium-high heat. If using bamboo skewers, soak in water for 20 minutes to prevent burning.
03 - Thread marinated chicken, zucchini slices, pineapple chunks, and red bell pepper pieces alternately onto skewers, distributing ingredients evenly.
04 - Place skewers on the grill and cook for 12 to 15 minutes, turning occasionally, until chicken is cooked through and lightly charred on all sides.
05 - Remove kabobs from grill and let rest for 2 minutes. Garnish with freshly chopped herbs if desired and serve immediately.
