This is from the restaurant chain California Pizza Kitchen. I had to make my own because they keep changing their menu and taking this soup off of it altogether. What a shame, now I have to make a whole pot and eat it until Im guilty of glutony. I like the caramelized leeks because they lend a lot of flavor to the soup. Once I accidentally over caramelized it (very brown), I thought it made the soup even better but maybe its because I am used to burnt food.
