In a separate pot over medium heat, bring the broth to a boil. In a separate large bowl, combine the ground beef, ground pork, 3 eggs, bread crumbs, basil, parsley and 1/2 cup Parmesan. Mix well and form into bite-size balls. Drop the balls into the broth. Add escarole into broth. When meatballs rise to the top, they are cooked, about 6 to 7 minutes. When escarole is wilted it is done. In a separate bowl, combine the remaining 5 eggs with the remaining 1 cup of cheese. Pour this mixture into the soup, stirring continuously, until the egg is cooked.
