01 - In a mixing bowl, dissolve granulated sugar and active dry yeast in warm water. Let the mixture stand for 5 minutes until the surface becomes bubbly.
02 - Add all-purpose flour, olive oil, and salt to the yeast mixture. Mix until a dough forms, then knead by hand or with a dough hook for 5 to 7 minutes until smooth and elastic. Cover and allow to rise in a warm place for 1 hour or until the dough has doubled in size.
03 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
04 - On a lightly floured surface, roll the risen dough into a rectangle approximately 10 by 14 inches.
05 - Evenly distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder over the surface of the dough.
06 - Starting from the long edge, roll the dough into a tight log. Slice the log crosswise into 12 even pieces.
07 - Transfer the rolls seam-side down onto the prepared baking sheet. Brush tops 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 and baked through.
09 - Serve warm. Present with marinara sauce on the side for dipping, if desired.
