Well this came from a friend at work. We were talking about Mexican food and I told him that I really like Enchiladas but it took so much time to make them. Well he told me about what his Grandmother did after she got older and the family got bigger. Well as time went by she was getting tired of all the work to make enchiladas so she started to make a Casserole instead of individual enchiladas and so he passed this on to me about 10 years ago. Mighty good I say. Very traditional taste with less work.
