Add one ounce of Italian dressing to a bowl.
Add 2 tbsp of grated Parmesan cheese.
Add 1 tsp of grated garlic.
Stir everything together.
Add the chicken to a zip lock bag and pour the sauce over it. The chicken is filleted, but slices would work too. Marinade overnight for maximum tenderness.
Cook chicken as normal (Until it reaches 160 Fahrenheit internal) and serve with your favorite side. If you want to know how to make the sauce, pasta, or cook the chicken, check out my other guides.
