Melt the last tablespoon of
butter in a large nonstick sauté pan over high heat. While the
butter is melting, lightly beat the eggs and
season with
salt and
pepper. Add the eggs to the melted
butter. Using a rubber spatula, quickly fold the edges into the center as they
cook. When the bottom is cooked and the top still slightly liquid, garnish the center with two-thirds of the
liver mixture. Fold the omelet and then turn upside down on a heated plate. Using the spatula, make a shallow cut down the center of the omelet. Spread the edges of the cut slightly and fill with the remaining
chicken livers.
