4 medium potatoes
4 or
5 eggs
1 medium onion
1/4 l of olive oil
Salt

Peel, wash and dry the potatoes.Cut in thin slices and place in a deep pan with olive oil at medium heat so that they cook slowly. Add the finely chopped onion. Fry slowly with the potatoes until they are soft and beginning to brown. It is best to stir using a skimming spoon to cut up the vegetables. After 10 minutes strain off the oil. Beat the eggs with a pinch of salt in an earthenware bowl. Add the potato and onion mix. Put the pan back on the heat with a little of the oil and add the egg and potato mix. Cover the pan and leave to cook on a low flame for 5 to 10 minutes until the bottom begins to brown. Turn the omelette upside down using a lid and then put it back in the pan on the other side so that it slowly sets. It should brown on both sides.

Serve on a round plate or serving dish, hot or cold. If you want to use it for a picnic or cut it up you should use more potatoes so that it is thicker and easier to carry and cut. In this case, eat cold.
