Tortilla is simply prepared and tastes quite delicious.

Ingredients for four people:
1 olive oil
800g potatoes
2 large onions
6 eggs
Salt and pepper

Preparation:
Peel the potatoes and onions. Cut the potatoes into cubes or thin slices.
Cut the onions into fine dice.

Heat about 4 tablespoons of olive oil in the pan, add the potatoes and onions and cook whilst moving the food about for 20-25 minutes on medium heat. The potatoes should not roasted. Possibly precook the potatoes slightly.
Flavour the whole thing with salt and pepper.
Thoroughly blend the eggs in and the potatoes and then add the onions. Leave to stand for about an hour.
Heat 4-5 tb of olive oil in the pan and let the mass falter at medium heat for about 5-8.

Then rotate the tortilla. To do this one needs to cover the pan with a large plate and rotate the tortilla on the plate. Allow it to then glide back into the pan and finish cooking.

The tortilla can be tasted cold or warm. For serving it will need to be converted into pie pieces.

Tip: You may add paprika, pepper salami or the like.
