01 - Combine softened cream cheese, mayonnaise, garlic powder, salt, and pepper in a small mixing bowl. Blend until uniformly smooth.
02 - Arrange tortillas on a clean cutting board. Evenly spread the cream cheese blend onto each tortilla, leaving a 1/2-inch border around the edge.
03 - Distribute baby spinach leaves in a single layer over the cream cheese on each tortilla.
04 - Lay cheese slices, optional deli turkey or ham, carrots, and bell pepper evenly atop the spinach layer.
05 - Starting from one edge, tightly roll each tortilla into a log to ensure coherent layers.
06 - Secure each roll in plastic wrap and refrigerate for a minimum of 30 minutes to firm up before slicing.
07 - Remove plastic wrap and cut each roll crosswise into 1-inch pinwheels using a sharp knife for clean slices.
08 - Place pinwheels cut side up on a serving platter. Serve chilled or at room temperature as desired.
