Combine olive oil, white wine vinegar, Parmesan cheese, minced garlic, sugar, Italian seasoning, black pepper, and salt in a gallon-sized zip-top bag.
Add chicken to the marinade bag, remove excess air, and seal.
Massage the bag gently to ensure chicken is coated in the marinade.
Refrigerate chicken in the marinade for 4-8 hours.
Preheat grill to 450 degrees F.
Remove chicken from the marinade and place it on the grill. Grill chicken for 5-7 minutes per side or until the internal temperature reaches 165°F. Use a meat thermometer for accuracy.
Remove the chicken from the grill and let it rest for 5-10 minutes before serving.
Enjoy with your favorite side dishes.
