Preheat oven to 350 degrees. Place breadcrumbs, Parmesan cheese, salt and pepper in a flat dish. Have beaten eggs in a shallow dish so chicken can be totally covered.
Place chicken in flour, then in beaten eggs, then in the breadcrumbs. Place each breast into a baking dish. Combine butter, garlic and mushrooms in a small skillet and saute about 3 minutes.
Pour butter mixture over chicken breasts, cover and bake in preheated oven for about 20 minutes. This is fast and easy and I usually serve rice and a vegetable with this dish. Makes 4 servings. Enjoy!
