A French-inspired light and refreshing tuna salad with a gourmet touch. Use high quality tuna, olive oil, and tomatoes for best flavor. Either garden-fresh tomatoes or "melted" cherry tomatoes work beautifully--each gives a different, equally delicious flavor profile. Serve the tuna salad as a main course, or stuff lettuce cups with it, or pile it atop sourdough toast. You can't go wrong!
