Do not use a cast iron skillet unless it has an enamel coating because it could change the color of the eggs to a greenish color.
If you want your eggs to be a little runnier, cook them to your liking. Cooking time will vary depending on how you like your eggs; just do not overcook them.
Cheese is optional and eggs can be eaten plain, or topped with sliced avocado, salsa or your favorite hot sauce.
Eggs will continue cooking in the pan, so be sure to remove it from the heat and take it out of the pan to stop the cooking process.
For fluffier eggs beat them vigorously to whip air into them.
