01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together the gluten-free flour blend, baking powder, salt, and dried oregano until evenly combined.
03 - Add the Greek yogurt and olive oil to the dry mixture. Stir until a smooth dough forms, kneading lightly on a floured surface if necessary to bring it together.
04 - Transfer the dough to a surface dusted with gluten-free flour. Roll it out into a rectangle measuring approximately 12 by 8 inches.
05 - Spread the pizza sauce evenly across the surface of the dough, leaving a 1/2-inch border along all edges. Sprinkle the mozzarella, pepperoni or bell peppers, Parmesan, and Italian herbs evenly over the sauce.
06 - Starting from the long side, carefully roll the dough into a tight log. Using a sharp knife or dough cutter, slice the log into 16 even pieces.
07 - Place the rolls spiral-side up on the prepared baking sheet. Brush the tops lightly with olive oil and sprinkle with garlic powder.
08 - Bake for 18 to 20 minutes, until the rolls are golden brown on top and the cheese is melted and bubbly.
09 - Allow the rolls to cool for 5 minutes on the baking sheet before serving. Best enjoyed warm.
