So we purchased a Honey Baked Ham for the holidays from the Honey Baked Ham Store (their version is the best). After serving slices Christmas Day, there was plenty left for using in other recipes. Here’s one sure to please. A panini press is not necessary. You can do all of these steps in a non-stick skillet. I used olive oil for brushing. Melted butter would be great also. Leftover fresh cranberry sauce added a nice component. Other ingredients are: stone ground mustard and sharp cheddar slices. I think warming the cold meat up is important. I grill marked the ham on the press before assembling the sandwich.
