Peel and finely dice the onion and garlic. Heat the oil in a large pan. Fry the onion and garlic for about 2 minutes. Add tomatoes, bring to the boil and simmer for about 10 minutes. Season to taste with salt, pepper and 1 pinch of sugar.
With a spoon press 4 hollows into the tomatoes. Break open the eggs and spread them in the hollows. Leave to set in the closed pan over medium heat for about 10 minutes.
Wash parsley, shake dry, chop coarsely. Crumble cheese. Sprinkle the pan with both. Flatbread tastes good with it.
