What you'll need:
1 can cream of chicken soup (or celery or mushroom)
2 cans water
1 package of onion soup
2 heads of fresh broccoli, chopped (or 1/2 pkg of frozen)
1 cup uncooked rice
2 chicken breasts, chopped
So, like I said, throw everything into your pyrex, mix well, add the chicken, cover her with foil, and throw her in the oven at 350 for 1 hour. Easy enough.
