White beans and ham is another favorite. Use a smoked ham hock to flavor the soup, and then remove the hock and pull out the good ham, dice it up, and return it to the soup. Rosemary is a good herb to use with bean soup. https://www.allrecipes.com/recipe/21403/ham-and-beans/
Just a note: I really like Olive Garden's sausage and potato soup, too. That is good stuff.
