Thank goodness for Google! I found Healthified Mom's Southwest Hashbrown Casserole. The ingredient list didn't look complicated - in fact, it looked easy peasy. The only thing that I was a little "turned off" by was the Cream of Mushroom. I don't tend to use a lot of "cream of" anything, but I knew the hubs would like this. I did make a few modifications to suit our tastes: 1/2 cup fat free sour cream (instead of 1 cup), 1/2 can French's fried onions (instead of a whole can). I also used reduced fat Cream of Mushroom and cheddar cheese. I served the Southwest Hashbrown Casserole with Green Giant Simply Steam Baby Vegetable Medley.
The assessment from the hubs - "... We have to have this again..." My assessment - I would reduce the sour cream a little more. I may consider reducing the cheese in the mixture and use some of it on top. Otherwise, it was the perfect comfort food with pretty low calories.
