Yes, the grill in the summer is versatile — cooking nearly every meal, if you want. But pizza? Pizza? Yes, you heard right — you can now cook pizza on your grill, thanks to the Grill-Top Pizza Stone ($100). The stone, specifically for gas grills, is made of porous clay, which sits on a raised stainless steel platform. There is a back-splash to keep all the goodies on the stone, and a thermometer to keep an eye on temperatures.
