Preheat oven to 400°F (204°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine self-rising flour and Greek yogurt until a dough forms.

Knead the dough on a lightly floured surface for 2 minutes until smooth and elastic.

Roll the dough into a large rectangle approximately 1/4 inch thick.

Spread pizza sauce over the dough, leaving a 1/2 inch border on all sides.

Evenly distribute mozzarella cheese and turkey pepperoni slices over the sauce.

Sprinkle with oregano and garlic powder.

Roll the dough tightly into a cylinder starting from the long edge.

Slice the cylinder into 12 equal rolls using a sharp knife.

Place rolls onto the baking sheet and brush the surfaces with the beaten egg.

Bake for 15 to 18 minutes until the crust is golden brown.

Rest for 5 minutes before serving.
