1 whole yellow onion

5-6 large eggs

1-2 cups of olive oil for pan frying

Salt to taste

Peel and chop the onion into thin slices. Put potatoes and onions into a bowl and mix them together. Salt the mixture.

In a large, heavy, non-stick frying pan, heat the olive oil on medium high heat. Carefully place the potato and onion mixture into the frying pan, spreading them evenly over the surface. The oil should almost cover the potatoes. You may need to turn down the heat slightly, so the potatoes do not burn.

Leave in the pan until the potatoes are cooked. If you can poke a piece of potato with a knife and it easily breaks in two, your potatoes are done. Remove from the pan with a slotted spoon or spatula and allow oil to drain.

Pour 1-2 Tbsp of olive oil into a medium 20cm, non-stick frying pan and heat on medium heat. Be careful not to get the pan too hot because the oil will burn - or the tortilla will! When hot, stir the potato onion mixture once more and “pour” into the pan and spread out evenly. Allow the egg to cook around the edges. Then you can carefully lift up one side of the omelet to check if the egg has slightly “browned.” The inside of the mixture should not be completely cooked and the egg will still be runny.

When the mixture has browned on the bottom, you are ready to turn it over to cook the other side. Take the frying pan to a sink. Place a large dinner plate upside down over the frying pan. With one hand on the frying pan handle and the other on top of the plate to hold it steady, quickly turn the frying pan over and the omelet will “fall” onto the plate. Place the frying pan back on the range and put just enough oil to cover the bottom of the pan. Let the pan warm for 30 seconds or so. Now slide the omelet into the frying pan. Use the spatula to shape the sides of the omelet. Let the omelet cook for 3-4 minutes. Turn the heat off and let the tortilla sit in the pan for 2 minutes.
