Broccoli Rice Casserole

Another one from Grandma B.

1 cup minute rice
2 boxes cut brocoli (I assume small boxes of frozen brocoli, thawed and drained)
1 can cream chicken soup
1/2 cup milk
1 can water chestnuts
1/4 cup chopped onion
1 8oz jar of cheez wiz
1 Tbsp of butter

Mix all ingredients together except for the butter. Cut up and dot butter on top of casserole.

Bake at 350 degrees for 45 minutes
