01 - Combine sugar and active dry yeast with warm water in a mixing bowl. Allow to rest for 5 minutes until the mixture becomes frothy.
02 - Incorporate all-purpose flour, olive oil, and salt into the yeast mixture. Mix and knead for 5 to 7 minutes to achieve a smooth texture. Cover the dough and leave to rise in a warm environment for 1 hour, or until doubled in size.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper for easy release.
04 - Transfer dough onto a lightly floured surface and roll into a 10x14-inch rectangle.
05 - Evenly distribute mozzarella cheese, sliced pepperoni, dried oregano, and garlic powder over the surface of the dough.
06 - Starting at the longer edge, tightly roll up the dough into a log. Slice the log into 12 even pieces.
07 - Place the rolls seam-side down on the prepared baking sheet. Brush each roll with melted butter and sprinkle with grated Parmesan cheese.
08 - Bake for 18 to 20 minutes, or until breadsticks are golden and thoroughly cooked.
09 - Serve warm, accompanied by marinara sauce for dipping if desired.
