From the 1974 Better Homes and Gardens After Work Cookbook, this is faux Mexican cuisine. Very odd. It just has a paragraph of directions, too, no list of ingredients or anything. would you eat this?
Here are the directions:
In skillet combine 2 cups cubed cooked chicken; one 11-oz. can condensed Cheddar cheese soup; one 8-oz. can tomatoes, cut up; 1/2 cup uncooked packaged precooked rice; and 2 tablespoons chopped canned green chili peppers. Drain sauce from one 15-oz. can tamales and add sauce to chicken mixture. Cover; simmer 5 minutes over low heat. Meanwhile, remove husks from tamales; cut tamales in 1-inch pieces. Place pieces atop chicken mixture. Cover; cook over low heat till tamales are heated through, about 10 minutes. Serves 4.
So, where do we get the tamales? I think you’d be spending more time finding the ingredients for this one than would be worth it. If I found tamales, I’d eat those with vegetables and rice.

Seems to me I bought tamales once because I remember unwrapping them. But I agree, I don’t think I’d search for them again to make this. Just make spaghetti or something easy like that rather than a strange concoction like this when you get home from work.
