Zucchini Soup

My friend Joan (see 2-6-09) gave me the recipe for Zucchini Soup several years ago and it has become a favorite around our house.  Tonight I hosted the Moms' dinner here at home and almost forgot to make it.  We were in Costco when I realized that I had left it off the menu.  We quickly added it on.  The only thing I needed to buy was half and half and 6 lbs. of zucchini.  It is delicious and I always double the recipe so I can send some home with my guests.
