Add small amount of butter or cooking oil to small skillet and preheat to medium-high heat until butter/oil is melted. Add eggs and allow them to cover the bottom of the pan. Using your best omelet flipping skills, loosen the egg from the sides and bottom of the pan with a spatula and flip it over to cook the other side. Cut into 4 equal pieces. If you can’t keep the eggs together or it sticks, just scramble the eggs at will and we’ll worry about keeping the eggs on the sandwich later.
