Slow Cooker - You can absolutely make this in the slow cooker, and I often do! Simply add the cooked sausage, onion, and carrots to a slow cooker along with the garlic, seasoning, tomatoes, and broth. Cook low for 7-8 hours or high for 3-4 hours. Then add the chopped kale and pasta and cook for 15-20 more minutes, until the pasta is softened and then stir in the cream and Parmesan cheese. Enjoy!
