Try serving this simple soup with a light herb cheese (such as Boursin) and crackers. The freshest strawberries you can get will enhance the effect.
Place the strawberries in a medium bowl. Sprinkle with sugar and salt; toss well. Place the strawberry mixture in a blender or food processor, and process until smooth. Cover the mixture and chill for 2 hours. Stir in champagne. Serve the soup immediately. Sprinkle with black pepper, if desired.
