Wash the parsley, shake dry and finely chop. Knead the dumpling dough, egg and ham cubes with the parsley. Shape the mixture into 1-2 rolls (5-6 cm in diameter). Cut into 18 to 20 thalers. Heat the lard in portions in a pan. Fry the potato thalers in 2-3 portions on each side for about 4-5 minutes until golden brown.
