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, cohesive dough forms. Knead lightly on a floured surface if needed to bring it together.
04 - Transfer the dough to a surface dusted with gluten-free flour. Roll it out into a 12 x 8-inch rectangle, maintaining an even thickness throughout.
05 - Spread the pizza sauce evenly across the dough, leaving a 1/2-inch border on all edges. Sprinkle the mozzarella, pepperoni, Parmesan, and Italian herbs over the sauce in an even layer.
06 - Starting from the long side, roll the dough up tightly into a log. Using a sharp knife or dough cutter, slice into 16 equal pieces.
07 - Place the rolls spiral-side up on the prepared baking sheet, spacing them about 1 inch apart. Brush the tops lightly with olive oil and dust with garlic powder.
08 - Bake for 18 to 20 minutes, or until the rolls are golden brown on top and the cheese is melted and bubbly.
09 - Allow the rolls to cool on the baking sheet for 5 minutes before serving. Serve warm with additional marinara sauce for dipping if desired.
