01 - In a small bowl, combine the cream cheese, mayonnaise, Italian seasoning, and garlic powder. Mix thoroughly until smooth and well blended.
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 cream cheese. Top with 1-2 slices of provolone cheese.
04 - Distribute a handful of spinach leaves, strips of roasted red pepper, and black olives (if using) evenly across the meats and cheese.
05 - Starting from one edge, roll the tortilla tightly, keeping the filling compact as you work.
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 pinwheels using a sharp knife. Arrange on a serving platter and serve chilled or at room temperature.
