Season contents of slow cooker with pepper. Add broth and ham hock if using and stir everything well. Cover slow cooker and cook on LOW for 6-8 hours, or until meat and beans are tender.

Heat a large, deep skillet over medium-high heat and add oil. Add as much kale as will fit and sprinkle with a little salt. Cook until wilted down enough to add more kale, along with a bit more salt. Repeat until all kale is in pan and just cooked through. Stop cooking while kale is still bright green. Transfer to serving bowl.
