Tender and juicy meatballs in a warm, smoky, and earthy broth with kale and some sweet tomatoes and Kabocha make for a satisfying and comforting Mexican-inspired soup.

You can also add uncooked cubed kabocha, simply add it as you bring the soup to a boil and simmer until tender, it should be cooked through about the time the kale is cooked through, 15 minutes.
