Creating your Grilled Ranch Garlic Parmesan Chicken Skewers is simple when you follow these easy steps:

1. Prepare the Marinade: In a large bowl, combine the ranch dressing, garlic powder, Parmesan cheese, olive oil, black pepper, and salt. Mix well.
2. Marinate the Chicken: Add the chicken pieces to the marinade, ensuring they are evenly coated. Cover the bowl and let it marinate for at least 20 minutes (or up to overnight in the refrigerator for more flavor).
3. Preheat the Grill: While the chicken is marinating, preheat your grill to medium-high heat (about 375°F to 400°F).
4. Skewer the Ingredients: Thread the marinated chicken onto skewers, alternating with bell pepper and onion chunks, if using. Leave a little space between each piece for even cooking.
5. Grill the Skewers: Place skewers on the preheated grill and cook for 15-20 minutes, turning occasionally until chicken is cooked through (internal temperature should reach 165°F).
6. Remove and Rest: Once cooked, remove the skewers from the grill and let them rest for 5 minutes to allow the juices to redistribute.
7. Serve Hot: Enjoy hot off the grill, garnished with extra Parmesan cheese if desired.

These simple yet effective steps will ensure that your skewers turn out perfectly every time!
