Reserve 8oz of broth and refrigerate until chilled. Bring remaining broth to a simmer. In a bowl, beat eggs with a whisk. Add parsley, bread crumbs, Parmesan cheese, chilled broth, and nutmeg to the eggs and mix thoroughly. Add contents of the bowl slowly into the broth whisking constantly. Cook about 3-4min until the ingredients start to float and look done. Add salt and pepper to taste. Serve immediately.
