Tilt the skillet and run a spatula or fork under the edge of the omelet, then jerk the skillet sharply to loosen omelet from bottom of skillet. Add favorite filling, if desired. Fold the portion of the omelet nearest you just to the center. Allow for a portion of the omelet to slide up the side of the skillet. Turn the omelet onto a warm plate, flipping folded portion of omelet over so the far side is on the bottom. Sprinkle with salt and pepper.
