Fresh Veggie Tuna Salad Sandwich
In a small bowl, mix together tuna, mayonnaise, Dijon mustard, lemon juice, and salt and pepper to taste. Stir in carrots, red bell peppers, and celery. Place 6 torn leaves of romaine lettuce on half the slices of bread. Spoon tuna mixture on top of the lettuce slices. Place another torn lettuce slice on each tuna sandwich and cover with remaining bread slices. Wrap sandwiches in colorful plastic wrap or wax paper and keep chilled. Your sandwiches are now picnic-ready!
