Directions:
For the Soup:
In a skillet over medium heat, cook the sausage until browned and crumbled, about 5–6 minutes, then drain excess fat.
In your slow cooker, add browned sausage, onion, carrots, celery, garlic, beans, chicken broth, tomatoes (if using), seasonings, and bay leaves, then stir to combine.
Cover and cook on low for 6 to 7 hours or high for 3 to 4 hours, until vegetables are tender.
Start a time for stirring in chopped kale during the last 20 to 30 minutes to cook, until just wilted.
For the Topping:
Mix together the ingredients in a small bowl, and top the soup as you serve in bowls. Enjoy!
