01 - Combine softened cream cheese, mayonnaise, garlic powder, salt, and black pepper in a small mixing bowl using a spoon or spatula until smooth and homogenous.
02 - Arrange tortillas on a clean cutting board and evenly coat each with the cream cheese mixture, leaving a half-inch border around the edges.
03 - Distribute baby spinach leaves in a single layer over the spread surface of each tortilla.
04 - Place cheese slices, and, if desired, deli turkey or ham atop the spinach. Layer with julienned carrot and sliced red bell pepper for even distribution.
05 - Firmly roll each tortilla from one edge to form a uniform log shape.
06 - Wrap each rolled tortilla tightly in plastic wrap and refrigerate for a minimum of 30 minutes to allow the contents to set.
07 - Remove chilled rolls from plastic wrap. Using a sharp knife, slice each roll crosswise into 1-inch wide pinwheels.
08 - Arrange pinwheels cut side up on a serving platter and present chilled or at ambient temperature.
