Creamy Potatoes and Ham Au Gratin

We had a wonderful Christmas dinner. Lots of great food and wonderful laughs with family. Cleanup even went quickly with lots of helping hands. But then we are always left with the inevitable leftovers. This year I needed a fairly quick, but still wonderful, recipe to use with leftover ham. Ree Drummond to the rescue! I found this easy recipe on her site Pioneer Woman and also on Food Network. Of course I had to make it. I mean, how can ham, potatoes, and cheese not be good, right?
