Mix 3 cups cold leftover mashed potatoes with 1 egg, 1 heaping cup of cheddar cheese, some chives (or other herbs), salt and pepper.
Scoop into balls on a parchment-lined baking sheet and refrigerate until solid.
Heat oven to 400F.
Pour some cornstarch into a dish.
Roll the balls in the cornstarch and return to the baking sheet.
Spray with cooking spray.
Bake for 15-20 minutes or until golden.
If you want them darker you can put under the broiler for a few minutes.
Let cool 5 minutes and enjoy!
