In a large bowl, combine the cubed chicken breast, olive oil, minced garlic, paprika, salt, and black pepper. Mix well to coat the chicken. Cover and let marinate in the refrigerator for at least 30 minutes.

Prepare the Vegetables

While the chicken is marinating, prepare the vegetables. Cube the bell peppers and red onion, and slice the zucchini.

Assemble the Kabobs

Once marinated, thread the chicken and vegetables onto the skewers, alternating between chicken, bell peppers, red onion, and zucchini. Leave a small space between each piece for even cooking.

Grill the Kabobs

Preheat the grill to medium-high heat. Place the skewers on the grill and cook for about 10-12 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.

Serve

Remove the kabobs from the grill and let them rest for a few minutes. Serve warm with your favorite dipping sauce or over rice.
