01 - Combine sugar and active dry yeast in warm water and allow to rest for 5 minutes until foamy.

05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly over the dough.
06 - Starting from the longer edge, roll dough tightly into a log. Slice into 12 equal pieces.
07 - Place each roll seam-side down on the prepared baking sheet. Brush with melted butter and sprinkle with grated Parmesan cheese.
08 - Bake for 18 to 20 minutes, or until breadsticks are golden and fully cooked.
09 - Serve warm, accompanied by marinara sauce if desired.
