This was originally a stove-top recipe I learned way back in school home economics class, which I converted to the slow cooker. Follow the recipe up to step three, but instead of putting the browned meat in the slow cooker, put it on a plate and return it to the pot with the stock in step three. Bring to a boil and then simmer gently for about 1 hour. Add the potatoes and then simmer for 30 minutes or until the potatoes are cooked through. Add the beans in the last 10 minutes or serve them o the side.
