Coat bottom of cast iron skillet and use your fingertips to flatten dough until it is 1/8 inch from edge of skillet. Cover tightly with plastic wrap and let rest until slightly puffy, about 1 1/2 hours.
30 minutes before baking adjust oven rack to lowest position and heat oven to 400 degrees.
Spread 1/2 cup sauce evenly over top of dough, leaving 1/2 inch border. Sprinkle Monterey Jack cheese evenly over border. Press cheese into side of skillet forming 1/2 inch to 3/4 inch wall. Evenly sprinkle cheese over sauce.
Bake until cheese at edge of skillet is well browned, 25 to 30 minutes.
Transfer skillet to stovetop. Let cool for 3 minutes. Check bottom of pizza crust. Place over medium high heat and cook until crust browned. Transfer to wire rack and let cool for 10 minutes.
