Zucchini omelette

Sometimes, for a change, like last night, instead of the magnificent "tortilla de papas" (potato omelette) I make this variant with zucchini. I fry in a pan with olive oil a sliced zucchini and a white onion. In a bowl I beat 6 eggs until frothy (you can separately beat the white and the yolk for better results). Then I add to it sea salt, crumbled feta cheese (Mount Vikos from Greece) and the drained zucchini and onion, mixing it all and then I put a table spoon of olive oil in the pan and the mixture cooking it at medium temperature for a couple of minutes each side (so I flip it with two pans).

It is simply delicious.
