Creating these delicious kebabs is simple and straightforward. Follow these steps to achieve the perfect result:

1. Prepare the Marinade:
   In a large bowl, combine 2 tablespoons of olive oil, 2 teaspoons of garlic powder, 1 teaspoon of paprika, and salt and pepper to taste. Mix well to ensure all ingredients are thoroughly combined.
2. Marinate the Chicken and Vegetables:
   Add the cubed chicken, chopped bell pepper, sliced zucchini, and chunked red onion to the bowl. Toss the ingredients until the chicken and vegetables are evenly coated with the marinade.
3. Thread onto Skewers:
   Take your soaked skewers and begin threading the chicken and vegetables alternately, ensuring an even distribution of ingredients.
4. Preheat Your Cooking Device:
   Preheat your grill or oven to medium-high heat, approximately 350°F to 400°F (175°C to 205°C).
5. Cook the Kebabs:
   Place the skewers on the grill or in the oven. Cook for 10-15 minutes, turning occasionally to ensure even cooking. The chicken should be fully cooked through, with no pink in the center.
