Sounded like a fun concept, especially since I'm without an oven right now.
'Buzzings of a Queen Bee' is one of my all-time favorite bloggers and this is where I got the idea. I learned that it is VERY important to roll the dough out thin, as it burns very quickly and for those of us who like thick crusted pizza and left ours that way, we ate it blackened. Otherwise they would have been awesome.

I used this pizza sauce recipe...it's got a kick and next time I may lay off using as many red pepper flakes...but great none the less.

We'll definitely try this again.
A big big thanks to Dutch Boy who was VERY patient with me during this process and manned the grill with finesse.
