Place the dumpling bread in a large bowl. Whisk together the milk, eggs, salt and pepper and then mix with the dumpling bread.
Sauté the "speck", onion and half of the parsley in a small frying pan with a little oil and add the remaining parsley and celery to the bread. Mix well and leave the dumpling bread to soak for a while.
Mix in the flour and form into dumplings with wet hands.
Bring the water to the boil, salt, add the dumplings and half-covered leave to simmer gently for 15-20 minutes.
Tip:
Tastes great with coleslaw!
