Begin by cutting the 1.5 lbs of boneless, skinless chicken breasts into 1-inch cubes.

In a separate bowl, combine 1/4 cup of olive oil, 3 cloves of minced garlic, 1/2 cup of grated Parmesan cheese, 1 tablespoon of dried Italian seasoning, 1 teaspoon of salt, and 1/2 teaspoon of black pepper.

Add the cubed chicken to the marinade, ensuring every piece is well-coated. Cover the bowl and let it marinate for 30 minutes.

Soak your wooden skewers in water for at least 30 minutes. Once soaked, thread the marinated chicken pieces onto the skewers.

Preheat your grill to medium-high heat, around 400°F (200°C). Place the skewers on the grill and cook for about 12 minutes, turning occasionally.

Remove the skewers from the grill and let them rest for a couple of minutes, then sprinkle with 1 tablespoon of chopped fresh parsley.
