Totally changing this post. From what I understand, the only thing gluten free about these pizzas is the crust before it is handled by the Domino's workers. The pizzas are assembled in the same place that the rest of their pizzas are assembled. The National Foundation of Celiac Awareness has given them an Amber designation. What this means is Domino's Pizza has agreed to train their help up front to tell anyone buying the "gluten free pizza" that it is not gluten free. The training is up front, not in the back with the making of the pizzas. So the bottom line is if you don't mind eating gluten, go ahead and eat the new Domino's gluten free pizza.
Watch the video below if you want, but you really need to go listen to the podcast from Blog Talk Radio, linked below, where Jules Shepard from Jules Gluten Free interviewed Alice Baste, a spokesperson for the NFCA, concerning their reasons for the Amber designation.
