Another kid fave (including me when I was growing up!) that is very easy, very fast, and inexpensive.
2 cans cream of chicken soup
1 large can cooked chicken (do not drain)
1 1/3 c Minute Rice
Chow Mein noodles
Combine soup, chicken, rice, and 1 soup can full of water in a large saucepan. Heat to boiling. Cover, and reduce heat to low. Cook 7 minutes. Serve over Chow Mein noodles.
