Creating Chicken Kabob is straightforward if you follow these easy steps:

1. Prepare Marinade: In a large mixing bowl, combine olive oil, lemon juice, minced garlic, cumin, smoked paprika, salt, and black pepper. Whisk until well blended.
2. Marinate Chicken: Add the chicken cubes to the marinade, ensuring they are well coated. Cover and refrigerate for at least 30 minutes or up to 1 hour for maximum flavor.
3. Prepare Vegetables: While the chicken is marinating, cut the bell pepper, onion, and zucchini into appropriate sizes for skewering.
4. Assemble Skewers: Thread the marinated chicken and vegetables onto skewers, alternating between chicken and vegetables for a colorful presentation.
5. Preheat Grill: Preheat your grill to medium-high heat, approximately 400°F (200°C).
6. Grill Kabobs: Place the skewers on the preheated grill. Cook for about 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
7. Check for Doneness: The internal temperature of the chicken should reach 165°F (75°C). If necessary, cook a few minutes longer.
8. Rest Before Serving: Once cooked, remove the kabobs from the grill and let them rest for a few minutes before serving.

These simple steps will guide you in creating delicious Chicken Kabob that is sure to impress.
