There's also an option to "crazy crust it," where you can have them brush the crust with a garlic butter-flavored spread ("buttery flavor") and sprinkle on a generous amount of parmesan cheese in the same fashion as their Crazy Bread.
I ordered one with sausage and was offered the crazy crust option for no charge when I arrived to pick it up so I went for it.
Regardless, the sausage was good. It's not the ideal coarsely-ground, loosely-formed stuff at nicer places, but it was juicy and flavorful with a pinch of herby flavor. It was a little gummy though but I've found that to be the norm among the big chains. They didn't skimp on the coverage either (it probably helped that I wasn't paying $5 for a pizza).
The crust was the weakest portion here. It was soft, dense, chewy, and a little spongy like bread... fresh-baked bread but it wasn't very pizza-ish. There wasn't any of the irregular air pockets and not a hint of crispness to be found. It was soft from crust to core. The stuffed crust ended up feeling like a generic cheese-filled breadstick. The saving grace was the buttery parmesan "crazy crust" which added a much welcome hit of flavor.
Overall, the Stuffed Crust was just too bready for my liking. I would definitely get the sausage again though and can always get Crazy Bread for the same flavor sans the cheese.
