I do my omelettes slightly differently - I agree with the saut�ing of the veg fillings beforehand (sliced potato, mushrooms, onions, peppers, chillies etc) in the same frying pan (in a little olive oil, then remove the veg when cooked and place on a piece of kitchen paper to remove the excess oil. Turn on the grill at this stage. I then beat up a couple of eggs (for a one person omelette), pass them through a sieve (fine mesh) to collect any stringy bits or egg shell pieces, pouring straight into the frying pan. Leave on a gentle heat for a few minutes and when the edges start to set, push these in towards the middle slightly, to thicken up the edges. As the eggs set, I gently slide a wooden spatula underneath the omelette to loosen it from the pan. When the underside starts to turn golden brown, I gently place the veg fillings back over the top of the almost cooked egg, sprinkle with grated strong cheddar and place the frying pan under the preheated grill to brown and set the egg properly. It should puff up and turn golden brown. Fold in half and serve up on a warm plate. Delicious with buttery mashed potato, cooked sweetcorn and a doorstep of fresh crusty bread ! I sometimes add a few slices of fresh tomato along with the cheddar - this gives a lovely juicy omelette.
