Well, the folks at Panera did respond to my missive, as follows:

Dear Sean,
Thank you for contacting Panera Bread about our Tomato and Fresh Mozzarella Salad. We have good news for you. While the salad is not currently a featured menu item, many of our operators make it available to customers as a special request. Please ask a manager or associate if it is available in your local bakery-cafe.

Thanks again for contacting us. We appreciate your business and value your comments.
Sincerely,
Alice
Customer Comment Coordinator
