Soak Skewers: If using wooden skewers, submerge them in water for at least 30 minutes before cooking to prevent them from burning on the grill.

Make the Marinade: In a large bowl, whisk together the olive oil, minced garlic, grated Parmesan cheese, Italian seasoning, salt, and black pepper.

Coat the Chicken: Add the cubed chicken to the bowl with the marinade. Toss until every piece of chicken is evenly coated. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes, or up to 4 hours for deeper flavor.

Thread the Skewers: Preheat your grill to medium-high heat (about 400°F or 200°C). Thread the marinated chicken pieces onto the soaked skewers, leaving a little space between each piece to ensure even cooking.

Grill to Perfection: Place the skewers on the preheated grill. Cook for 12-15 minutes, turning occasionally, until the chicken is cooked through and has beautiful grill marks. The internal temperature should reach 165°F (74°C).

Rest and Serve: Remove the skewers from the grill and let them rest for 5 minutes before serving. This allows the juices to redistribute throughout the chicken, ensuring every bite is moist and flavorful.
