After my wife went to Italy, she told me about the pizza in Florence. I made pizzas for a few weeks until she proclaimed that I got it right. Basically, it's thin crust with sauce and mozzarella. But, it's not that easy. To get it done right, I had to pre-cook the crust. Got my BBQ pit up to 600*F, then stuck the raw dough on a pizza stone sitting on the grill. Let it cook for a few minutes, just to get rid of the rawness. Then, removed it and put on the sauce and cheese.
Threw a smattering of corn meal on the stone, then baked it until the cheese started browning. The crust was crispy and flaky, but didn't get soggy from the sauce (because it was pre-cooked).
