Cooking pizza on the grill gives it a smoky, authentic flavor impossible to achieve anywhere else. The Charcoal Companion FLEX Grill Sheets make it easier to make pizza on your grill. Perfect for either fresh or store-bought 12 pizzas. Durable and heat resistant to 600F, the sheets are reusable many times. Clean up is simple; once the sheets have cooled, place them in the top rack of the dishwasher or wipe them down with a damp cloth. The sheets also prevent buildup on grill grates so more time is spent grilling pizza rather than cleaning the grill.
