The Studios Catering Company had a vegetable panini that was yummy, FYI. It had mushrooms, zucchini, roasted red peppers, forget what else. All Ears says it has provolone cheese but I honestly didn't remember any, so I assume there's not much.
The vegetable wrap for Picnic in the Park (you might also be able to get it at Tamu Tamu or at the place where they have grab and go at AK, if the picnic isn't available) was lettuce, carrots, portobello mushrooms, and I think cucumbers, in vinaigrette. It was okay but it really needed some roasted red peppers or something for a little zing.
