Preheat oven to 500 degrees F. If you have one, place a pizza stone on the bottom rack of the oven.
Roll dough into a 12-inch circle, about 1/2-inch thick. Dust pizza peel or baking sheet with cornmeal. Place rolled out dough on peel.
Brush dough with olive oil. Smear minced garlic over dough. Top with Italian seasoning, ricotta, Parmesan, crawfish tails, and sliced mozzarella.
Bake for about 8 to 10 minutes, or until cheese is bubbling and the edges are golden brown.
Yield: 1 (12-inch) pizza, serving 2 to 3
