Pizza Hut offers pizza made with Udi's crust. All the toppings and sauces are gluten free, except for the Alfredo sauce. On their website there is a gluten free FAQ and describes how their staff is trained and how it is prepped. It comes uncut to the table to further avoid CC, and is cooked and brought in a separate tray. I was pleasantly surprised to find out the gf crust isn't even more expensive.
