01 - Combine softened cream cheese, chopped roasted red peppers, shredded cheese, Italian seasoning, and black pepper in a medium bowl. Mix thoroughly until completely smooth and evenly incorporated.
02 - Place a tortilla on a flat work surface. Spread one-quarter of the cream cheese mixture evenly across the entire surface, extending completely to the edges for uniform coverage.
03 - Distribute equal portions of salami, ham, and pepperoni over the cream cheese base, arranging slices in a single overlapping layer without gaps.
04 - Scatter one-quarter of the baby spinach leaves evenly over the meat layer, pressing gently to adhere.
05 - Roll the tortilla tightly from one edge to the opposite edge, applying firm pressure to create a compact log. Repeat the process with remaining tortillas and fillings.
06 - Wrap each roll securely in plastic wrap and refrigerate for minimum 30 minutes or up to 24 hours. Chilling firms the texture for cleaner cuts.
07 - Remove rolls from refrigerator and unwrap. Using a sharp knife, cut each roll crosswise into 1-inch rounds, wiping the blade clean between slices for neat presentation.
08 - Arrange pinwheels on a serving platter in concentric circles or rows. Serve chilled or allow to reach room temperature for 15 minutes before serving. Offer marinara sauce on the side for dipping if desired.
