How to Make It
Combine all ingredients in a 6-quart oval slow cooker. Cover and cook on LOW 9 hours. Serve with Confetti Chowchow, if desired.
Make it ahead: You can make the collard greens up to 2 days in advance. Refrigerate them in the slow-cooker insert. Allow the insert to stand at room temperature for 30 minutes before returning it to the slow cooker to reheat the greens. (Immediately heating a chilled insert could cause it to crack.)
