The secret ingredient in this delicious green gazpacho? Ciabatta bread! It gives body to the liquid and thickens the cucumber, melon, and grape juices. Serve as a light summer dinner or as the appetizer for a dinner party. If you’re making the soup ahead, make sure to taste the seasoning before serving, since chilling can change the saltiness of cold food. Pair with a crisp white wine or rosé, and some good tunes on the stereo, because, summer.
