Onion Soup

I made onion soup from Mark Bittman's How to Cook everything Vegetarian last night.  It was good last night, I had never made or had onion soup before.  The soup was even better after sitting in the fridge overnight and re-warmed for lunch today!  It's like a revelation- really good!  The hardest part was slicing the onions.  If you need to make a soup that is easy and full of flavor, make this one!  Unfortunately I don't have a link to the actual recipe.  I checked this book out from my local library though.
