Instructions
In a medium bowl combine the first 4 ingredients and make into 1-inch meatballs. Add oil to a large skillet and lightly brown meatballs over medium-low heat, on both sides. Note: The meatballs shouldn't be cooked through all the way, but just browned on the outside.
Add to the slow cooker: meatballs, onion, garlic, potato cubes, red pepper flakes, black pepper, salt, chicken broth, and milk, and stir just to combine. Cover and cook on low 6 to 8 hours.
Add kale and cook just until wilted, approximately 10 -15 minutes.
Optional: For a thicker soup, combine cornstarch and cold milk, stir until smooth and add to slow cooker the last 20 minutes of cooking time.
