01 - In a mixing bowl, combine granulated sugar and active dry yeast with warm water. Let stand for 5 minutes until foamy.
02 - Incorporate all-purpose flour, olive oil, and salt into the yeast mixture. Mix and knead on a lightly floured surface for 5 to 7 minutes until the dough turns smooth and elastic. Cover and let the dough rise in a warm place for 1 hour or until doubled in volume.
03 - Heat oven to 400°F. Line a baking sheet with parchment paper.
04 - Roll the dough out on a floured surface into a rectangle measuring 10 by 14 inches.
05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly over the surface of the rolled dough.
06 - Starting with the long edge, roll the dough tightly into a log. Slice into 12 equal pieces.
07 - Arrange the rolls seam-side down on the prepared baking sheet. Brush each roll with melted butter and sprinkle with grated Parmesan cheese.
08 - Bake in the preheated oven for 18 to 20 minutes, or until the breadsticks are golden brown and cooked through.
09 - Serve the breadsticks warm, accompanied by marinara sauce for dipping if desired.
