01 - In a small bowl, combine softened cream cheese, mayonnaise, garlic powder, salt, and black pepper. Stir until a smooth and uniform spread is achieved.
02 - Lay tortillas flat on a clean work surface. Evenly distribute and spread the cream cheese mixture over each tortilla, leaving a 1/2-inch border around the edges.
03 - Arrange a single layer of baby spinach leaves on each tortilla. Top with cheese slices, then add the optional deli meat if desired. Scatter shredded carrot and thinly sliced bell pepper evenly over the surface.
04 - Starting from one edge, roll each tortilla tightly into a log shape, ensuring fillings stay evenly distributed.
05 - Wrap each roll securely in plastic wrap and refrigerate for at least 30 minutes to help maintain shape during slicing.
06 - Remove plastic wrap and use a sharp knife to slice each roll into 1-inch thick pinwheel pieces.
07 - Arrange the pinwheels on a platter. Serve chilled or at room temperature according to preference.
