01 - Combine sugar and active dry yeast with warm water in a mixing bowl. Allow to stand for 5 minutes until the mixture becomes foamy.
02 - Add flour, olive oil, and salt to the activated yeast. Mix thoroughly, then knead by hand or with a dough hook for 5 to 7 minutes until the dough is smooth and elastic. Cover and let rise in a warm area for 1 hour, or until doubled in size.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
04 - On a floured surface, roll the dough into a rectangle measuring 10 by 14 inches.
05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly across the dough surface.
06 - Starting from the long side, tightly roll the dough into a log. Cut the log crosswise into 12 equal portions.
07 - Place 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, until the breadsticks are golden and cooked through.
09 - Serve warm with marinara sauce for dipping, if desired.
