This is a perfect light and tasty sandwich. Pair quality bread and butter with this ready-in-a-jiffy salad and add lettuce for crunch. Use a crispy baguette or soft roll if you prefer or,if you're not a bread-eater,wash some iceberg lettuce,fashion the leaves into"cups"and fill with your mixture. Chopped cooked king prawns and shredded roast chicken are great stand-ins for the tuna,while other fabulous optional extras include roast tomato and diced cooked potato. Enjoy!
