whisk 3 eggs with little salt & pepper (do not add water or milk, not needed).. add little oil in medium size frying pan, make sure oil is hot (very slightly smoking) before adding your mixture to the frying pan, continuely mixing in the frying pan until it starts to set on bottom, slightly turn the heat down and then with help of a spatula to loosen around the edges, flip omelette over to cook other side. At this stage I add, while still in pan, the filling (either cheese, mushroom, ham, bacon or peppers .. or mixture of each). Then again using the spatula fold one half over to the other (covering the filling) and serve on plate ... best fluffy omelette ever !!
