01 - Combine cream cheese, mayonnaise, Italian seasoning, and garlic powder in a small bowl. Mix thoroughly until smooth and fully incorporated.
02 - Place a flour tortilla on a clean work surface. Spread one-quarter of the herb 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 provolone slices, ensuring even coverage.
04 - Distribute a handful of spinach leaves, roasted red pepper strips, and black olives if desired across the meat and cheese layer.
05 - Starting from one edge, roll the tortilla tightly and firmly, keeping all fillings securely inside the roll.
06 - Repeat the spreading, layering, and rolling process with the remaining three tortillas and filling ingredients.
07 - Wrap each rolled tortilla securely in plastic wrap. Refrigerate for a minimum of 1 hour to allow the rolls to firm and set for clean slicing.
08 - Remove plastic wrap and cut each roll into 6 even pinwheels using a sharp knife. Arrange on a serving platter and serve chilled or at room temperature.
