The first time I made this I ended up making it twice in one week my family liked it so much!
This can be a great start for chicken parmigiana if you prefer, simply heat spaghetti sauce, add a slice of cheese during the last few minutes of baking, and serve with noodles.
Preheat oven to 350 degrees. Spray a glass dish with non-stick cooking spray. In one shallow bowl, beat egg. In a separate bowl, combine bread crumbs, parmesan cheese, italian seasoning, black pepper, and garlic powder. Dip both sides of chicken breast in egg, then in breading mixture and place in glass dish. Repeat with remaining chicken. Sprinkle remainder of breading mixture over chicken in dish.
Cover with aluminum foil and bake for 25 minutes. Remove foil and bake an additional 10-20 minutes, until chicken is browned and no longer pink.
