Mix flour, eggs, 1 teaspoon of salt, nutmeg and mineral water to a smooth, thick dough. Let dough rest for 1-2 hours. Peel and chop onion and garlic. Clean, wash and chop the peppers.
Dab the meat dry and cut into strips. Fry them all around in hot oil. Add paprika, onion and garlic and fry for 3-5 minutes. Add stock and tomato puree, bring to the boil and simmer for about 10 minutes.
Season to taste with ketchup, salt and paprika. Boil up plenty of salted water for the spaetzle. Gradually place a portion of the spaetzle dough on a moistened kitchen board and scrape fine strips into the boiling salted water with a long knife.
Let it simmer at low heat until the spaetzle float on the surface. Take them out with a skimmer and let them drain in a sieve. Arrange the spaetzle with the shredded meat on a plate.
Wash parsley, dab dry and chop. Sprinkle over the spaetzle.
