Cook pasta shells as directed on package.

While pasta is cooking prepare Tomato-Basil Vinaigrette (recipe can be found in my profile).

Mix mayonnaise, basil, and salt in medium bowl. Stir in tuna, carrot, zucchini and onion until evenly mixed. Drain pasta. Rinse with cold water; drain. Fill each pasta shell with 1 tablespoon tuna mixture and top with 1/2 tablespoon of Tomato-Basil Vinaigrette.

These shells can be served either warm or cold. To serve warm: Place shells on a microwavable plate. Cover with plastic wrap. Microwave on high 2-3 minutes or until warm.
