The heat of summer is the perfect time to think about soup. Not hot soup, but cold. And when I think about cold soup, gazpacho quickly comes to mind. It has a complexity of flavors, but it's so simple to prepare, it's almost child's play.
I remember falling in love with it the first time I tried it in high school. Summer tomatoes, peppers, cucumbers - it's the ultimate summer standby that works in a bowl as well as a cup.
Gazpacho is the perfect lunch for summer, both filling and cooling during the heat of the day, or as a quick and cooling dinner at night. Either way - as a soup or a drink - you have a fresh-from-the-garden mixture that you can make a day ahead and forget about it until it's time to serve.
