In a medium mixing bowl combine the flour, salt, egg and milk. Mix until you produce a slightly sticky ball of dough. Flour the counter and roll out dough to 1/8 inch thickness. You want them very thin because they thicken when cooked.
Cut noodles (I use a pizza cutter) to desired size and place on wax paper. Let the noodles dry out on the counter for at least 1 hour before adding them to the soup.
About 30 minutes before serving soup, drop noodles in and cook. Add some fresh chopped parsley right before serving. Enjoy.
