Heat your skillet to medium high heat, cut your onion into large flat sided rings.

Heat a tablespoon of olive oil and place an onion ring in the center of the pan, flatten it as best you can with a spatula.

While holding the onion ring firmly against the pan crack an egg inside of the ring and cover.

Pour a tablespoon of water into the pan and re-cover to allow the steam to cook the top of the eggs.

Season to your liking and enjoy!
