I bought a large for $12.
As you can guess from the components, this is basically a pretty standard chicken pizza with the addition of pesto to the pizza sauce.
Papa John's thin crust (and that of Pizza Hut and Domino's, for that matter) isn't really like any traditional pizza (and definitely not like a margherita pizza, despite how they decided to name this one). Which is not to say that it's bad; just different. It reminds me more of pie crust or cracker bread more than anything. There's a layered, crisp quality but also a slightly soft chew intermixed here and there.
The tomatoes add an additional, slightly fresher tang to the pizza sauce, while the pesto chimes in with a mild basil note. It's a very slight change but a pleasant one.
