Place the beef in a medium pot and add the water. Bring to a boil and then reduce the heat to low. Add the rest of the ingredients, except the pasta and cilantro.
Cook for about 45 minutes or until beef is completely tender. Add the pasta and cilantro to the soup. Cook for about 8 minutes more. Serve hot with lime and avocado on the side.
