Preheat your oven to 375 degrees F (190 degrees C).
In a large bowl, combine mashed potatoes, stuffing, shredded turkey, Parmesan cheese, beaten egg, bread crumbs, salt, and black pepper. Mix well until all ingredients are thoroughly combined.
Form the mixture into 1-inch balls and place them on a baking sheet lined with parchment paper.
Bake in the preheated oven for 15-20 minutes, or until the balls are golden brown.
