How to Make It
In a 4- to 6-quart slow cooker, combine the beans, kielbasa, broth, tomatoes (and their juices), onion, garlic, rosemary, and 1 cup water.
Cover and cook until the beans are tender, on low for 7 to 8 hours or on high for 5 to 6 hours (this will shorten total recipe time).
Just before serving, stir in the spinach. Serve with the bread.
