I'm gonna assume your at home.
Cut up some bacon into a frying pan with fry light and add some sliced onion. Fry for a couple of minutes. Meanwhile in a jug or something mix 3 eggs, a dollop of fromage frais, half your cheese allowance and salt and pepper. Mix it all together with a fork and pour over the bacon and onion. Sprinkle remainder of cheese and stick it under the grill to brown up. it's my favourite omelette and on an extra easy day I have it with some baked beans....yummeh!
