Heat the oil in a pan (non stick if possible) on a medium heat.
½ tbsp olive oil
Crack the eggs into a bowl and mix well.
Pour the egg mix into the pan.
Using a spatula, ruffle the omelette so it doesn't stick.
Let it cook for about 3 minutes.
Here's the important part: when the egg mixture looks nearly cooked (but there's still just a tiny bit of runny egg left) drop on the cheese, if using.
½ cup cheddar cheese, grated
Fold one half of the omelette on top of the other.
Slide it on to a plate - the heat from closing the omelette will finish cooking the inside.
Season with salt and pepper (be sure to do this after cooking - the flavour comes out so much more!).
Salt and pepper to taste
Enjoy your perfect omelette.
