Preheat the oven to 400 F degrees. Cut the chicken breast in 4 pieces. Whisk the egg whites in a bowl until lightly foamy and dip the chicken breast pieces in it. Combine the bread crumbs with Italian seasoned bread crumbs, grated Parmesan, garlic powder and pepper and coat every piece of chicken breast. Make sure that every piece gets a lot of bread crumbs Parmesan mixture. Put the chicken breast pieces in the pan covered with baking paper. Lightly spray with oil and bake for 20 minutes. Cover every piece with a slice of Mozzarella cheese and put it back into the oven for a few minutes more until the cheese is melted. Spread the tomato sauce over the cheese and sprinkle with chopped fresh basil. Garnish with steamed broccoli.
