Tips and Tricks
Keep the dough thin - Roll or stretch the dough evenly so it cooks through on the grill.Use room temperature dough - Room temperature dough is easier to stretch and less likely to spring back.Drain excess moisture from the zucchini - If the zucchini seems wet, pat it with paper towels before adding it to the pizza.Watch the crust closely - Grilled pizza cooks fast, so check the bottom often to prevent burning.
