I got this recipe from my first mother-in-law.
Place a couple of boneless chicken breasts (or 4 thighs or a breast and 2 thighs) in the bottom of a casserole dish. Combine 2 cups of grated cheddar cheese with 1 large can of cream of mushroom soup or 1 small can of cream of mushroom soup and 1 small can of cream of chicken soup. Bake at 350ºF for an hour. Serve over rice.
Frankly, I liked the sauce that came out of that over the rice better than I liked the chicken. Maybe I should try just combining COM with cheese and see what happens.
