We have a PIZZA STONE that we haven't tried yet, though Bob just saw a video on this VillaWare PizzaGrill BBQ Pizza Maker and it looked quite interesting. Although, this is less expensive alternative, ZaGrill Pizza Cooker.
While I was over at Amazon, they suggested a couple of books:
- Pizza on the Grill: 100 Feisty Fire-Roasted Recipes for Pizza & More
- Grilled Pizzas and Piadinas
- List of BBQ COOKBOOKS
