Wash the potatoes and cook in boiling water for about 20 minutes. Coldly rinse, peel and cut into slices. Clean, wash and chop the leek and peppers. Fry the potatoes, leek and peppers in 3 tablespoons of hot oil while turning for about 12 minutes.
Season with salt and pepper. In the meantime cut ham and gherkins into small cubes. Wash parsley, dab dry, pluck leaves from the stalks and, except for a few for garnishing, chop and mix with ham and gherkin cubes.
Fry eggs in remaining hot oil as fried eggs. Season with salt and arrange on the potato pan. Sprinkle with diced ham and cucumber. Serve garnished with remaining parsley.
