Mix together the ground meat, salt, parmesan and panko. Set aside until the soup is finished simmering. Use a small cookie scoop (any size between 1 and 2 ounces) to scoop the meatball mixture directly from the bowl and drop them into the soup. Once they are all in, simmer the meatball soup for 20 minutes.
Finish the soup.
Add the tortellini and simmer for another 8 minutes. Finish with fresh chopped parsley.
