I spent a few months looking for a good grilled pizza recipe awhile back. I eventually stumbled upon a version by Americas Test Kitchen, which actually turned out pretty darn good. It took me awhile to convince my wife and kids that I could make a pizza on my gas grill, but that didn't stop them from eating it. :) Actually, everybody I've mentioned it to is skeptical about it. Not sure if they doubt my skills or the concept in general. It's a fairly straight forward recipe, but there are a couple things that can easily be modified for your tastes.
