AU-GRATIN POTATOES WITH LEFT OVER HAM

Sliced Red Potatoes seasoned with salt and pepper, I added one cup of water and covered tightly with foil, cooked in over for 40 minutes at 375 degrees. 

Sliced Ham off of bone.

Diced Ham and removed skin and fat.

Add Butter(about 1/4 stick) to pan until it melts then

Whisk Milk, and Cornstarch over high heat for a few minutes until milk is warm.

Added 3 slices of American cheese and salt and pepper to taste. 

Cook on medium heat stirring constantly until thickens. 

(You can thin sauce with milk or if you need to thicken it whisk cold milk and cornstarch then add to sauce)

Add ham and sauce to Potatoes and return to oven covered for  approximately 20 minutes.
