Pasta on pizza—it's a thing. How have we never put this question to you pizza lovin' people before? Adding ziti or macaroni to pies seems to be a regional trend that is most prominent in the Long Island and New Jersey swatch of the pizza belt. But there are outliers too, like this spaghetti pizza in Grapevine, TX. And I recently noticed that some frozen pizza brands have introduced mac n cheese varieties to their lineup. Are you into the carb on carb pies?
