Arrange four pepperoni slices in a straight row on a clean cutting board or work surface, slightly overlapping each slice.
Fold the entire row in half lengthwise, keeping the slices slightly overlapped. You should have a flat edge along the bottom.
Starting at one end, gently roll the folded pepperoni into a tight spiral. You’ll have a small rose shape when you’re done.
Slide the pepperoni rose onto a skewer or toothpick, leaving about ½ inch at the bottom.
Gently slide a fresh basil leaf onto the skewer, positioning it just beneath the pepperoni rose.
Add a marinated mozzarella pearl to the bottom of the skewer.
Repeat with the remaining pepperoni, basil, and mozzarella until you’ve made all the skewers.
