How do you make delicious pizzas without using an oven?

Well, you can use microwave. I normally use microwave and it taste better than the one from oven. You can use your barbecue. This is very easy. If your grill is square or rectangular and the Pizza will not fit with the lid closed, cut it in half. Lay foil on the grate(s), and when the coals come up to temp, lay the pizza on top. It takes less time than in an oven, so peek in on it from every minute or so. The more often you do this, the better you will get at judging the time it will take.

Obviously, a barbecue will be better than a gas grill, and the pizza, even frozen has a more traditional taste, but gas works fine too. Keep in mind, that grill on your back patio is just an antique oven.
