Bring approx. 4 l salted water (1 teaspoon per litre) to the boil in a wide saucepan. Wash the herbs and shake dry. Chop parsley finely, cut chives into fine rolls.
Mix flour, eggs, 1/2 teaspoon salt and 75 ml water with the dough hooks of the mixer to a thick dough. Add herbs. Beat the dough with a wooden spoon until it bubbles. Place portions into a spaetzle press and press into boiling water.
Cook until the spaetzle rise to the surface, then lift them out and let them drain well.
Heat butter in a large frying pan. Fry the spaetzle for about 5 minutes while turning. Season to taste with salt, pepper and nutmeg.
