Mix the flour with the salt and garlic powder before adding the Greek yogurt. Use a fork to mix everything together until a crumbly dough begins to form. Empty the dough onto a flat surface and use your hands to bring everything together into a ball of dough. (You can also use a food processor or stand mixer for this step.)

Use your hands to press outward from the center of the dough, creating thicker edges for the crust than in the center. Be careful not to stretch the center too thin and create holes.

Preheat an oven to 500F or as hot as your oven will go and heat a large 12" cast iron skillet over medium-low heat.

Add the olive oil to the skillet and wait until you start to see a bit of smoke before carefully adding the pizza dough to the skillet.

Cook for 2-3 minutes until you begin to see color from the oil cooking into the dough before adding half the cheese. (This acts as a barrier to prevent any sogginess from the sauce and toppings.) Cook for another 2-3 minutes until the cheese begins to melt.

Spoon the pizza sauce on top of the dough and layer of melted cheese.

Add the remaining toppings and cheese. Be sure to get some cheese around the edges of the crust for golden brown edges. (Optional: Sprinkle with crushed red pepper and dried oregano.)

Put the cast iron pizza in the hot oven for 8-10 minutes until the cheese is fully melted and the edges are golden brown. Let the pizza cool for a few minutes before removing from the skillet to slice.
