Take 4 pieces of pepperoni and layer them halfway over each other on a flat surface. Fold them over in half, pressing as you fold. Then, start rolling them up from the edge until it is all rolled up. Add to the middle of a long toothpick or small wooden skewer.
Add basil leaves on each side of the rose as well as two mozzarella pearls to the ends to help secure it all.
Notes
Store. Place the assembled roses on a plate, cover them with plastic, and store them in the fridge for 2-3 days.
