Put oil or butter in pan and heat up. I cook on a medium heat. Salt, pepper and sprinkle basil. If you don't like a runny egg, break the yolk now with the edge of your spatula. When bottom of egg is fully cooked, flip egg over to cook other side. If you like a runny egg yolk be careful to not break it and flip gently.

Place cheese slices on top of the cooked side of the egg. When the cheese is melted it is usually done, if it isn't done to your liking cook a little longer.
