Remember those White Beans with Kale  we made a couple of days ago? Today, we’re going to use the leftover cooking liquid and some of the beans themselves to make a luscious soup.
If you have a fancy flavored oil, now’s the time to use it. I drizzled a touch of white truffle oil over my bowl of soup and it provided another dimension of earthiness. If you use it, don’t go crazy or you will overpower the soup. Just a hint will do.
Later in the week, we’ll be featuring the White Beans with Kale  in one more recipe – an appetizer.
