01 - In a small mixing bowl, thoroughly combine softened cream cheese, mayonnaise, garlic powder, salt, and pepper until smooth.
02 - Lay tortillas flat on a clean cutting board. Evenly spread the cream cheese mixture onto each tortilla, leaving a 1/2-inch border around the edges.
03 - Arrange spinach leaves in a single layer over the spread. Place cheese slices, followed by carrots and red bell pepper, distributing ingredients evenly.
04 - Starting at one edge, roll up each tortilla tightly into a secure log.
05 - Wrap each tortilla roll in plastic wrap and refrigerate for at least 30 minutes to firm.
06 - Remove plastic wrap and use a sharp knife to cut each roll into 1-inch pinwheels.
07 - Place pinwheel slices attractively on a platter and serve chilled or at room temperature.
