Broccoli Chicken Casserole

I made this one night while Ammon, Jillian and their kids were visiting. We all ate, were full, and had a few leftovers for lunch the next day.

Ingredients:
6-8 cooked chicken breasts, cubed or shredded
2 cups cooked rice
1 bunch steamed broccoli or 1 box frozen (I bought a bag of broccoli florets, steamed them and chopped them up a little since I don't like huge pieces of broccoli)
2 cans cream of something soup (chicken, mushroom, celery)
1 8 ounce container sour cream
2 cups grated cheddar cheese
salt and pepper to taste

Mix all ingredients in a casserole dish. Bake at 350 degrees for 15 minutes. (Everything is already cooked so it doesn't have to bake long, unless it has been frozen.)
