Created by chef fabio viviani of siena tavern in chicago, this vegetarian tomato-basil soup recipe takes full advantage of fresh tomatoes. Roma or plum tomatoes are fleshy, low in seeds and cheap--making them a good candidate for tomato soup. During peak season you may also see other suitable plum-shaped heirloom varieties at your farmers' market, but you can also ask for any low-seed, fleshy varieties they may have. While this silky soup is the perfect partner for grilled cheese sandwiches, the homemade croutons add an herby-crunchy accent that should not be missed.
