For the omelet, peel the potatoes, boil them and then turn them into a coarse mash. Chop the onion and fry in a little oil.
Press the garlic cloves into the pan and fry them a bit. In a bowl, beat the eggs with salt, parsley and cheese.
Then mix in the coarse mashed potatoes and fry together in the pan with the garlic and onions.
Stir constantly for a few minutes until the omelet is really firm. Then serve on a plate.
