Heat oven to 350°. Lightly grease an 8″ square or round baking pan with butter or cooking spray (you can also cook in a lightly greased cast iron skillet).
Roll out the dough into a rectangle (12″x18″). Brush the dough with the melted butter. Sprinkle with the shredded cheese and then the ham. Be sure to cover the dough all the way to the edges. I usually leave a 1″ edge at the top though. Roll up from the bottom to the top, pinching to seal the top edge. Cut roll into 2″ slices.
Place slices into greased pan. Sprinkle with a little additional cheese, if you feel the need (I almost always do). Bake for 25-30 minutes or until golden brown.
