Leftover mashed potatoes get a new lease on life -- and you get a morning-after Thanksgiving breakfast you'll actually want to cook. Adapted slightly from Greene on Greens (Workman Publishing Company, 1984). —Genius Recipes
Wash and trim the scallions, leaving about 2 inches of green stems. Cook in boiling water until tender, about 5 minutes. Drain and chop finely.
Place the scallions in a medium-sized bowl. Add the eggs, nutmeg, salt, pepper to taste, bread crumbs, and mashed potatoes. Mix well.
Heat the oils in a large skillet until hot but not smoking. (Searing the cakes quickly helps them stay together.) Shape the onion-potato mixture into patties, using 2 rounded tablespoons of the mixture for each patty. Sauté, about six at a time, until golden brown on both sides, 2 or 3 minutes per side. Keep warm while sautéing the remaining patties.
