This is a favorite recipe of mine that I got from a roommate years ago. It is also in the CCK cookbook on pg. 87 if you don't want to copy it from here. I use the low fat version of the soups, sour cream, and crackers, and it still tastes great!
3-4 cooked chicken breast (or 2 cans cooked chicken)
1 can cream of chicken soup
1 can cream of mushroom soup
1 cup sour cream
1 tablespoon poppy seeds
3/4 cup chopped onions
1 1/3 cup uncooked minute rice
1 cup water
1 roll of Ritz Crackers
1 cup grated cheddar cheese
1/4 - 1/3 cup water OR melted butter
Line 9x13 casserole dish with uncooked rice and pour 1 cup water over rice. Stir rice and water. Combine chicken, soups, sour cream, poppy seeds, and onions in a bowl. Pour soup mixture over rice and top with grated cheddar cheese. Crush crackers and moisten with water (or melted butter). Put crackers on top of casserole. Bake at 325 degrees for 35 minutes.
Side note: Because this dish has poppy seeds in it, a person could test positive of opium since opium is made from poppies. I know that sounds like a myth....but it happened to some dinner guests of mine.
