In a medium bowl, add the breadcrumbs and enough milk to thoroughly moisten the breadcrumbs, set aside.
In a separate large bowl, combine the beef, pork, herbs, garlic, 1 teaspoon of salt, pepper and 1/3 cup of parmesan cheese, mix gently with hands to combine. Squeeze out the excess milk from breadcrumbs, and add it to the meat mixture. Add the egg to the meat mixture and gently mix by hands to combine all of the ingredients together.
Add the broth and wine to large 8-quart (8-liter) stockpot, season to taste with salt and pepper. When it comes to a boil, take small portions of the meat and roll into bite-sized, spoon-able, balls (about the size of a quarter) and drop them into the hot broth one at a time. Add the kale and stir to gently to combine. Reduce to a medium simmer (periodically skimming any foam that rises to the top) and cook until the meatballs are cooked through and the flavors have had a chance to come together, about 45 minutes to an hour. When done, slowly stir in a tablespoon or two of parmesan cheese into the broth, stir well to combine. Taste and adjust the seasonings if needed. Soup can remain on the lowest heat setting for a few hours.
While the soup is cooking, bring a large pot of water to a boil. Generously salt the water and add the pasta. Cook according to the package directions. Drain and very briefly rinse the pasta to remove just some of the starch. Drizzle with olive oil and stir gently to prevent sticking, set aside.
To serve, spoon the desired amount of pasta into individual serving bowls and ladle the hot soup on top, garnish with freshly grated parmesan cheese. Serve hot.*
Notes
* Note that the pasta is cooked separately to provide you with control over the texture and quality of the soup. If the soup produces any leftovers, pasta that has been cooked and left in the soup will swell and become undesirably soggy, absorbing too much of the broth. However, if serving a crowd at the table, it is recommended to serve the pasta, meatballs and broth together in a soup taurine, noting the above if there are any leftovers.
