Baked Parmesan Chicken

4 boneless chicken breasts, pounded flat
melted butter
1/3 c. Italian bread crumbs
1/3 parmesan cheese
Mozzarella cheese or cheddar which is what I use
1 jar favorite marinara sauce

Dip chicken in melted butter and then dredge in combined bread crumbs and parmesan. Place in oven and bake for 30 min. or till close to done. Place mozzarella cheese over chicken, pour sauce over chicken and sprinkle with parmesan cheese. Bake till cheese is melted and sauce is warm.
