Preheat oven to 375 degrees F. Line a baking sheet with parchment paper.
Unroll and separate crescent rolls into triangles. Place on the baking sheet and add your sauce. Spread evenly, sprinkle some cheese, and add half a stick of mozzarella string cheese to large end of the crescent triangle.
Grab the wide end of the crescent triangle, roll up each triangle and tuck the ends underneath. Place the seam-side down on the baking sheet.
In a bowl, whisk the olive oil, salt, pepper, and garlic powder until combined. Brush the mixture on your pizza rolls. Bake for 12-14 minutes or until the tops are golden brown.
