Crack to eggs in a small bowl and beat with a fork until mixed well.
Heat an 8-inch non stick skillet over a medium low heat.
Melt the oil or butter in the pan and swirl it around to coat the bottom of the pan.
Add eggs to the pan and season with salt and pepper.
Gently move the eggs around the pan as they begin to set up. I like to pull the edges of the eggs towards the center of the pan, allowing the loose eggs to spill over.
Continue until your eggs have set up and you have a thin layer of loose egg on the top of the omelet.
Add cheese to one half of the omelette and fold the omelette onto itself to create a half moon. Slide out of the pan and enjoy.
Notes
*Never use a non stick cooking spray in your non-stick skillets. They will ruin your pans. Instead stick to a pat of butter or oil.
