Potato and Watercress Soup

  I bought 3 bunches of watercress from the Asian market and about the only thing that I wanted to do with it was make a soup!  So, I did.  I did a little research and found this recipe online.  It's pretty basic, but I wanted to make sure the flavor of the watercress came through.  Like always, I made a few changes of my own.  :)
