- Prep the Base: Place the beans, sweet potato, onion, garlic, carrots, celery, collard greens, and tomatoes into your slow cooker.
- Sprinkle in paprika, black pepper, thyme, oregano, cumin, and bay leaf. Pour in broth and vinegar. Stir to combine.
- Cook: On low: 7–8 hours or on high: 4–5 hours until beans are tender and creamy.
- Remove bay leaf. Taste and adjust with black pepper, a squeeze of lemon, or a splash more vinegar instead of salt. Serve.
