Place folded salami, mozzarella balls, grape tomatoes, and green olives on a skewer. Repeat with the remaining skewers and ingredients, switching the order of ingredients on each one for variety.
Place the skewers on a large circular serving platter or cutting board, overlapping them if needed to fit the size of the board. Tuck the rosemary sprigs underneath the skewers all around the wreath.
Refrigerate until ready to serve. Drizzle with balsamic glaze right before serving.
