Joy's Broccoli Chicken Casserole - my family LOVES this!! Mix 1 can cream of chicken soup with 1 cup of mayo. Add 4 cups cubed cooked chicken breasts. Line the bottom of a 9x13 pan with frozen broccoli and spread the chicken mixture on top. Separately, mix 1 sleeve of crushed Ritz or saltine crackers, 2 cups shredded cheddar cheese, and 1 stick of melted butter. Cover and bake for 25 minutes at 350, remove cover and bake another 15. YUMM-O!
