Remove the mozzarella balls from the tub. Place them on paper towels to remove as much excess liquid as possible while you prep the other ingredients.
Fold the salami slices in half. Then fold them into thirds to create a rectangular shape.
Add four to five ingredients to each skewer. Mix and match the ingredients so that there is some variety in the skewers. There are usually 22 to 26 mozzarella balls in a tub, so most skewers will have cheese but not all of them.
Once the skewers are assembled, arrange some of them in a circle/wreath shape in a single layer on a serving platter. Add the remaining skewers stacked on top of the base ring. Add fresh rosemary sprig around the wreath to decorate. Serve immediately or cover and chill until ready to serve.
Notes
If you can't find mini pepperoncini, you can buy regular-sized ones and cut them in half.
Try adding artichoke hearts, prosciutto, cubed cheese, or fresh basil leaves as alternative options for the skewers.
The skewers can be made up to 24 hours in advance and stored in the refrigerator in an airtight container with a paper towel lining the bottom of the container. I recommend assembling the skewers the same day you plan to serve them to avoid excess moisture from the mozzarella pooling on the board.
Nutritional information will vary by which ingredients to put on each skewer.
