In a bowl, mix together all dry ingredients very thoroughly (you want it to be as homogenized as possible). Add Greek yogurt, ultrafiltered milk, and olive oil. Stir until a thick batter forms (it will be wetter than traditional dough)
Line a half-sheet pan (13×18×1 inch) with parchment paper. Pour in the dough and spread evenly to the edges using a spatula
Bake dough at 375°F for 25-30 minutes until firm. Remove and let rest for 5 minutes
Spread tomato sauce evenly over the crust. Top with mozzarella, Parmigiano Reggiano, and turkey pepperoni slices. Finish with garlic powder and a light oil spray (an even spray adds ~5g of oil, and is accounted for in the macros)
Return to oven and bake at 375°F for ~8 minutes. Switch to broil and cook for an additional 3-6 minutes until the top is browned and bubbling.
Let cool slightly, then slice into evenly sized rectangles
