If you have leftover mashed potatoes, this would be the perfect recipe to use them up, OR you can cheat like I did, and use the boxed kind.
Mix your leftover mashed potatoes (or make up the boxed kind, enough to equal 2 cups), with the eggs, flour, salt and pepper and anything else you like.
Heat your frying pan, and either spray generously with cooking spray or use 2 Tablespoons of oil, and drop 1/4 cup for each pancake, and fry for a couple of minutes on both sides until golden brown.
Serve with your choice of toppings and enjoy!
