01 - Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, whisk together the gluten-free flour blend, baking powder, salt, and dried oregano until evenly distributed.
03 - Add the Greek yogurt and olive oil to the dry mixture. Stir until a smooth dough forms, kneading lightly with your hands if necessary to bring it together.
04 - Transfer the dough to a surface lightly dusted with gluten-free flour. Roll out into a 12x8-inch rectangle, maintaining an even thickness throughout.
05 - Spread the pizza sauce evenly across the dough, leaving a 1/2-inch border along all edges. Sprinkle the mozzarella, pepperoni, Parmesan, and Italian herbs over the sauce in an even layer.
06 - Starting from the long side, carefully roll the dough into a tight log. Using a sharp knife or dough cutter, slice into 16 even pieces.
07 - Place each roll spiral-side up on the prepared baking sheet. Lightly brush the tops with olive oil and sprinkle with garlic powder.
08 - Bake for 18 to 20 minutes until the rolls are golden brown and the cheese is bubbly and melted.
09 - Allow the rolls to cool for 5 minutes on the baking sheet before serving warm.
