01 - Combine cream cheese, mayonnaise, Italian seasoning, and garlic powder in a small bowl. Mix until smooth and thoroughly blended.
02 - Place a tortilla on a clean work surface. Spread one-quarter of the cream cheese mixture evenly across the entire surface, extending to the edges.
03 - Arrange 1 oz each of salami, pepperoni, and ham over the tortilla. Top with 1 to 2 slices of provolone cheese.
04 - Distribute a handful of spinach leaves, roasted red pepper strips, and black olives if desired evenly across the meat and cheese layer.
05 - Starting from one edge, roll the tortilla tightly, keeping the filling compact and secure.
06 - Repeat the process with remaining tortillas and fillings. Wrap each roll tightly in plastic wrap and refrigerate for at least 1 hour to firm.
07 - Remove from plastic wrap and slice each roll into 6 equal pinwheels using a sharp knife. Arrange on a serving platter. Serve chilled or at room temperature.
