01 - Combine cream cheese, mayonnaise, Italian seasoning, and garlic powder in a small bowl. Mix 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 1-2 provolone cheese slices, ensuring even distribution.
04 - Distribute a handful of baby spinach, strips of roasted red peppers, and black olives evenly over the meat and cheese layer.
05 - Starting from one edge, roll the tortilla tightly toward the opposite edge, maintaining firm pressure to keep the filling compact and secure.
06 - Continue the process with the remaining three tortillas and filling ingredients until all pinwheels are assembled.
07 - Wrap each rolled tortilla securely in plastic wrap. Refrigerate for at least 1 hour to allow the rolls to firm and hold their shape when sliced.
08 - Remove 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.
