Preheat oil to 350 degrees F.
Cut leftover stuffing into bite-sized cubes and set aside. In a small bowl whisk eggs and milk. Coat each stuffing bite with this egg wash, then dredge in the bread crumbs until fully coated and set aside. In a food processor blend cranberry sauce, pepper and walnuts and set aside. Once oil is at temperature fry each piece of stuffing until golden brown about 4 minutes. Drain on a paper towel and serve with cranberry pesto.
