Anna and I are lucky to have a grill in our backyard. Let that soak in for a minute: A backyard. In Manhattan. Pretty great stuff. In any event, pizza made on that grill turned out to be easy, fast, and really, really great.
Here's the trick: Emphasize what you do well, and accept help with the rest. In my case, that meant buying dough and fresh mozzarella and then tossing a few choice ingredients (homemade tomato sauce and fresh pesto) on top. This is not meant to be an exhaustive explanation of how to make pizza on the grill. Instead, I'll just pass on the single most important lesson: Make sure that grill is hot as can be.
