GF pizza is cooked in same oven as regular pizzas, so cross-contamination is highly possible. However, the GF sausage-crust pizza is made in a separate deep dish pan so cross-contam. is unlikely in their ovens. We’ve had this many times with no issues. Sausage crust is not on the menu so you have to ask for it. Tell them you have the “allergy” and they will be careful.
