Cut each rectangle into four slices and roll up each slice to form a finger. Place the fingers on the prepared baking sheet
Cut the pepperoni slices in half, then cut each half into four wedges.
Press one pepperoni wedge onto the end of each finger to make a finger nail.
Bake the breadsticks in the preheated oven for 8 to 10 minutes, until golden brown.
