Preheat Oven to 450 degrees Fahrenheit

Create a breading station by placing the flour in a shallow bowl, the egg in another bowl and the breadcrumbs in another bowl. Add salt and pepper into each one

Using a spoon, grab mashed potatoes in 1 tablespoon increments. Round them off into balls

Make an indentation inside each ball and add the cheese. Close it up again into a bowl

Coat the ball in the flour, then the egg and finally the breadcrumbs. If the ball deforms you can reroll with your hands

Place on a sheet pan lined with cooling rack. Using cooking spray, spray the cooling rack

Put the balls on top of the cooling rack and spray the tops and sides with cooking spray

Bake for 8-10 minutes or until browned and crispy

Serve with marinara sauce
