What to do With Leftover Mashed Potatoes: Potato Fritters

After Thanksgiving I had some leftover mashed potatoes; a simple way to transform them into a snack or part of a meal is to mix them with some egg, toss in chopped parsley and scallions, and fry them in real butter.

This was really simple and went well with a dollop of sour cream on top, much like what you'd do with German style potato pancakes.
