In a skillet, brown your pork sausage and onion and drain.
Place the beans, beef, and 6 cups of water in the slow cooker.
Add the remaining ingredients and stir gently.
Cover and cook on high for 4 to 5 hours or low for 8-10 hours. I like to stir the beans a couple of times during the cooking process. It seems the help the beans to cook consistency so that some aren't hard while others are mushy.
You can serve these beans with a slotted spoon for a side dish or with a ladle as a soup!
