Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a large bowl, mix the Greek yogurt, self-rising flour, protein powder, garlic powder, and Italian seasoning until a shaggy dough forms.

Turn the dough onto a lightly floured surface and knead for 2-3 minutes until smooth and elastic.

Roll out the dough into a rectangle about ¼ inch thick (approximately 12x8 inches).

Spread the marinara sauce evenly over the dough, leaving a ½-inch border around the edges.

Sprinkle the shredded mozzarella cheese and chopped pepperoni evenly over the sauce.

Starting from the long side, carefully roll the dough up tightly like a jelly roll.

Cut the roll into 8-10 equal pieces using a sharp knife or dental floss.

Place them cut-side up on the prepared baking sheet, spacing about 2 inches apart.

In a small bowl, mix the melted butter and garlic powder. Brush this mixture generously over the tops of the rolls.

Bake for 20-25 minutes until golden brown and cooked through.

Remove from the oven and immediately sprinkle with Parmesan cheese and fresh parsley. Serve warm with additional marinara sauce for dipping, if desired.
