01 - In a mixing bowl, dissolve sugar and active dry yeast in warm water. Allow the mixture to rest for 5 minutes until it becomes frothy.
02 - Incorporate all-purpose flour, olive oil, and salt into the yeast mixture. Mix until combined, then knead for 5 to 7 minutes until a smooth dough forms. Cover and allow to rise in a warm environment for 1 hour or until doubled in size.
03 - Set oven to 400°F. Line a baking sheet with parchment paper and lightly flour the work surface.
04 - Roll the dough into a 10 by 14-inch rectangle. Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly across the surface.
05 - Roll the dough tightly lengthwise to enclose the filling, then slice into 12 equal pieces.
06 - Place each roll seam-side down on the prepared baking sheet. Brush with melted butter and sprinkle with grated Parmesan cheese.
07 - Transfer to the oven and bake for 18 to 20 minutes, or until the breadsticks are deep golden brown and cooked through.
08 - Serve warm with marinara sauce for dipping, if desired.
