Extremely late to the thread, but I have been cooking on a weber ketttle grill for close to 25 years.
There's pretty much nothing that cannot be cooked or smoked on a kettle.
One of my favorites is thanksgiving turkey, but as of late, my weekend addiction is pizza made on my Master chef Weber kettle.
We purchase the dough at Shaws, but hand stretch it and all of the ingredients besides the dough is ours.
It takes about 20 minutes, cooked at almost 500 degrees, but it comes out awesome.
