I'm...going to be that "guy" and add that we have had cauliflower-crust pizza, and have bought frozen cauliflower crusts and topped them ourselves. It erases the SO's carb concern and honestly tastes fine to me. The consistency is different, but it's a reasonable alternative for us. Have you ever tried a quinoa crust? Or is that too carby? I found a recipe online but haven't gotten around to giving it a shot yet.
