1. Position the rack in the center of the oven and heat the oven to 400 degrees . If you're using a pizza stone, warm it on the rack for 30 minutes.
2. Lightly flour a large baking sheet or a pizza peel, then place the dough on top. Dimple and stretch the dough to fit your baking surface. Spread the beans evenly across the dough, leaving a 1/2-inch border. Scatter on the cheese and the corn, then spoon on tablespoon-size dollops of salsa.
3. Bake the pizza until the crust is brown and the cheese has melted and is beginning to bubble, about 20 minutes. Let the pie cool for 5 minutes before adding the avocado and cilantro.
