Yesterday, the farm stand presented me with all of the key ingredients for this soup -- tomatoes, zucchini, onions and garlic -- except the can of beans and hunk of cheese, both of which are staples in my pantry. My own garden basil, abundant and robust, found a happy home with the vegetables in this tomato, zucchini, white bean and basil soup. I added hardy thyme early in the cooking, and tossed the more delicate basil in at the end. Perfect for a summer lunch or supper, with some crusty bread on the side, this "skinny" soup comes together quickly. After all, with very fresh herbs and vegetables, you don't want to fuss over them.
