Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a medium mixing bowl, combine the Greek yogurt and self-rising flour, stirring until a shaggy dough forms.
Turn the dough onto a lightly floured surface and knead for 2-3 minutes until smooth and elastic.
Roll the dough out into a thin 10-inch circle and transfer it to the prepared baking sheet.
Cut 1 ounce of the mozzarella into thin strips and place them around the edge of the dough, about half an inch from the perimeter.
Fold the edge of the dough over the cheese strips and press firmly to seal, creating the stuffed crust border.
Spread the tomato sauce evenly over the center of the pizza, then sprinkle with garlic powder, dried oregano, sea salt, and black pepper.
Top with the remaining 1 ounce of shredded mozzarella and the turkey pepperoni slices.
Lightly brush the outer stuffed crust with olive oil to ensure a golden, crispy finish.
Bake for 12-15 minutes until the crust is browned and the cheese is bubbly and melted.
