Gather all ingredients on a clean surface.
Start with a skewer and thread a cherry tomato onto it.
Follow with a mozzarella ball, pushing it down to secure.
Add a Kalamata olive next.
Place a green olive on the skewer.
Add a folded slice of salami or prosciutto.
Repeat the process until the skewer is filled, leaving space at the ends.
Drizzle olive oil and balsamic vinegar over the assembled skewers.
Sprinkle with salt and pepper to taste.
Serve immediately or refrigerate until serving.
