Add the chopped collard greens to your slow cooker. They’ll look like a lot, but they cook down beautifully.
Add the onion, smoked paprika, umami seasoning, garlic powder, apple cider vinegar, brown sugar, salt, pepper, and red pepper flakes. Pour the vegetable broth in and then mix well.
Cover and cook on High for 5 to 6 hours.
Once the greens are tender adjust seasoning with more vinegar, salt, pepper, or a pinch of sugar.
Serve hot with cornbread—it’s practically a requirement.
