In a medium bowl, mix mashed potatoes, eggs, salt and pepper together.

Melt butter or heat oil in a frying pan over medium heat.

Shape small portions of the potato mixture in your hands until they resemble a flat burger patty.

Place potato “patties” into the pan and flip after 3 or 4 minutes, or when golden brown.

Serve with sour cream or your favorite garnish/condiment.
