For the spaetzle, whisk the eggs, mix with the sausage meat and breadcrumbs. Season with salt, pepper and nutmeg. In a large saucepan, bring water to a boil, turn down a bit.
Using a spaetzle slicer, quickly scrape the mixture into the slightly boiling water and simmer gently for about 5 minutes. Keep stirring to prevent the spaetzle from sticking.
Skim with a skimmer and serve as Brätspätzle soup.
