Wash parsley, dab dry and chop. Season potatoes with salt and pepper. Deglaze with cream, bring to the boil, cover and simmer at low heat for another 4 minutes. Season again with salt and pepper. In the meantime heat the remaining oil in a pan. Beat the eggs, carefully slide them into the pan and fry them at medium heat for about 3 minutes. Season with salt and pepper. Serve the potatoes sprinkled with ham, cucumber and parsley. Arrange eggs on the potatoes as desired or add them separately.
