Combine all of the ingredients in the slow cooker pot.
Put the cover on and let everything cook for 45 minutes on high. If you don't need it right away, feel free to leave it for longer on low, just make sure it's hot and the cheese has melted. Pause the cooking occasionally to give a quick stir.
Serve with rye bread wedges.
