In a large bowl, combine all ingredients for the meatballs with your hands and roll bite-sized meatballs; set aside.
Heat a soup pot over medium heat with olive oil, 2 turns of the pan. Add chopped celery, onions, garlic and bay, and partially cover to soften, 5 minutes. Add tomato paste and stir a minute then add stock and 2 cups water. Drop in Parm rind, bring soup to a gentle boil and add meatballs. Simmer a minute then add beans and pasta, and cook to al dente. Soup should be thick rather than brothy. Wilt in the kale then season with salt and pepper.
Serve in shallow bowls topped with cheese and a drizzle of EVOO.
