Trillian, King Ranch Casserole is a great tasting Tex Mex dish. It has been made, personally, for over 40 years. A little variation, of course, but still tasty. The Pioneer Woman, IIRC, has her own version of King Ranch Casserole. Don’t forget the Guacamole and sour cream :)
Do you have a link to her recipe? I did a search and can’t find it on her site. I found a recipe for Italian chicken soup that looks good though.
