I got this off an internet site years ago and it's my favorite Mexican dish to make. It was from Roy Clark in Midwest Living Oct 1984. I have also made it with shredded chicken breast, and the last couple of times I made it I added a can of drained, rinsed light kidney beans. It's so yummy, honest! I lighten it up just a little using Campbell's "healthy" cream of chicken soup and skim or low fat milk. I also don't add the entire pack of taco seasoning...maybe about 3/4....but it's a taste preference.
