Ingredients: 4 eggs, 2 medium potatoes sliced thinly, little bit of chopped onions, salt and spices to taste, olive oil.
Instructions: In medium heat pour about 1/4 cup of olive oil on your pan, pour the potatoes and cook until lightly golden, add the onion, cook. Once cooked, place the potatoes over a paper towel to drain out some of the oil. Mix the potatoes with the beaten eggs and add salt and spices to taste. Once the potatoes are folded into the eggs, pour the mixture back on your pan on medium - high heat, cover the pan. Once the tortilla is half way cooked, transfer into another pan by flipping it carefully to cook the other side. Place the lid on the other pan.
