Cheesy Crouton Chicken

My mom has made this many times, so I looked for her recipe but I didn't have everything on hand, so I improvised.  It tasted great.

Cheesy Crouton Chicken

1 bag frozen chicken breasts - thawed and trimmed
1 can cream of chicken soup
1/2 cup milk
6 slice provolone cheese
1/2 bag croutons - crushed

Place chicken in a 9x13" baking dish.  Mix soup and milk and pour over chicken.  Top breasts with cheese slices, cover with foil, and bake at 325° for 45 minutes.  Uncover, sprinkle with crouton crumbs, and bake for 15 more minutes.
