Mix together the parmesan cheese, Italian seasoning and garlic powder in a large shallow bowl or dish. Run the chicken breasts under cold water, then roll wet chicken in the seasoning mixture to coat.

Place coated chicken breasts on a lightly greased baking sheet. Bake for 25 to 30 minutes or until chicken is thoroughly cooked. Serve with spaghetti sauce and pasta.
