If your dough is refrigerated, bring it up to room temperature for 30 minutes or so.
Pre-heat your oven to 400 ºF.
Coat your cast-iron skillet with olive oil.
Place your dough ball in the center of the cast iron skillet. Use your fingertips to flatten the dough until it is even and just barely touches the sides of the skillet.
Spread your sauce over the dough, but leave about 1/2 inch around the sides bare.
Using your fingers, press the Monterey Jack cheese into the side of the skillet. Form a wall about an inch tall around the edge.
Spread the mozzarella evenly over the sauce.
Spread your toppings over the mozzarella.
Bake in a 400 ºF oven for 30 minutes.
Remove the skillet from the oven and let it sit for about 5 minutes. Then take a knife and run it around the edge. Use a thin spatula to sneak a peek at the bottom of the pizza. You want it to be browned.
If it is not browned, then put the skillet on the stovetop over medium heat for about 5 minutes to brown it.
Transfer the pizza out of the cast iron skillet to a plate to cool for a few minutes and serve.
