Celery Root, Cabbage, White Bean, and Potato Soup

I realize that for some of you who are experiencing very warm early spring weather, soup might not appeal to you, but for those of us on the West Coast where things are still slightly rainy/snowy/cloudy, a big bowl of soup can be just what you feel like for dinner. The picture here probably doesn't do the flavors of this soup justice - while simple, the way the celery root, cabbage, potato, and white bean work together is superb, and even better with a topping of parmesan cheese and a drizzle of olive oil to finish it off. I've been getting more cabbage in my CSA box which has inspired me to try to use it in different ways, but my favorite way to use it is still in soup. Even if you think you don't like cabbage, give this a try.  It has become one of the very few things I make which I actually repeat. You can also make this without the celery root if you can't find it and just use more potatoes.

Extra virgin olive oil
2 lb. celery root, peeled and diced into small pieces
