Preheat the oven to 375 degrees. Line a baking sheet with a silpat mat.
Unroll the crescent dough and separate into eight triangles.
Place some pepperoni minis on the big side of the triangle followed by some mozzarella cheese.
Carefully roll the crescent dough, starting from the big side making sure to pinch and tuck the ends so the cheese doesn't spill out.
Place onto the prepared baking sheet and into the oven to bake for 10-12 minutes. Remove from the oven and serve immediately with marinara sauce. Enjoy.
