01 - Combine softened cream cheese, mayonnaise, garlic powder, salt, and pepper in a small mixing bowl. Stir until smooth and evenly blended.
02 - Lay tortillas flat on a clean cutting board. Evenly spread the cream cheese mixture over each tortilla, leaving a 1/2-inch border around the edges.
03 - Arrange baby spinach leaves in a single layer on top of the spread. Lay cheese slices over the spinach, then distribute carrot and red bell pepper evenly.
04 - If preferred, place deli turkey or ham slices over the vegetables and cheese.
05 - Starting from one edge, roll each tortilla into a tight log. Repeat with all tortillas.
06 - Wrap each rolled tortilla in plastic wrap and refrigerate for at least 30 minutes to set.
07 - Remove plastic wrap and use a sharp knife to cut each roll into 1-inch pinwheels.
08 - Arrange pinwheels on a serving platter. Serve chilled or at room temperature.
