Drain the marinated mozzarella, artichoke hearts, olives, and pepperoncinis well to avoid soggy skewers.
Fold each salami slice in half, then in half again to create a ruffled, easy-to-skewer shape.
Thread the onto a skewer, alternating colors and textures. A great pattern is: green olive, salami, tomato, mozzarella ball, Kalamata olive, artichoke heart, and pepperoncini.
Repeat the process until all 12 skewers are assembled.
Arrange the finished Antipasto Kebabs on a platter.
Serve immediately or cover and refrigerate for up to 24 hours.
