Yes! There are some things you can do to get ahead. Make the meatballs and keep them in the fridge or freezer in a freezer-safe bag until you're ready to use them. Flash-freeze them solid first if you plan to freeze them. You can also make the soup base, but don't add pasta or kale. Make the soup, and keep it in an airtight container for up to a few days ahead. When you're ready to eat, then add the pasta and kale to wilt and heat through along with the meatballs.
