01 - Combine the cream cheese, mayonnaise, Italian seasoning, and garlic powder in a small bowl. Mix thoroughly until smooth and well incorporated.
02 - Place a tortilla flat 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, ensuring even coverage.
04 - Distribute a handful of spinach leaves, several strips of roasted red pepper, and black olives if desired across the meat and cheese layer.
05 - Starting from one edge, roll the tortilla tightly toward the opposite edge, applying gentle pressure to keep the filling compact and secure.
06 - Continue the process with the remaining three tortillas, dividing all fillings equally among them.
07 - Wrap each completed roll tightly in plastic wrap. Refrigerate for a minimum of 1 hour to allow the fillings to set and the rolls to firm.
08 - Remove the plastic wrap and slice each roll into 6 equal pinwheels using a sharp knife. Arrange on a serving platter and serve chilled or at room temperature.
