1Preheat the oven to 450°F; put the oil and butter into a cast iron skillet and put it in the oven while it heats.
2Meanwhile, whisk together the eggs, flour, and milk (use 2 eggs, 1/2 cup each milk and flour for about a 6 inch skillet, 3 eggs and 3/4 cup each milk and flour for a larger 9 inch skillet). Pour the batter into the hot skillet and slide it back into the oven. Bake for 15 minutes, or until the pancake is puffed and golden.
3Fill with warmed turkey, stuffing, peas and gravy. Serves 2-4, depending on pan size and quantity of leftovers.
