Position the rack in the center of the oven and heat the oven to 400°. If you're using a pizza stone, warm it on the rack for 30 minutes.
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.
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.
