My old Betty Crocker cookbook (1975) had a recipe for a chicken casserole that I just loved. It was called "Chicken Casserole Deluxe", and used a box of Betty Crocker's Noodles Romanoff. Since that product was discontinued, I've really missed this casserole, so I've tried to duplicate it. I think this is pretty darn close. I've also made it low fat. You can use full-fat if you like.
