Lay the flour tortillas flat on a clean surface or cutting board.
In a medium bowl, mix the softened cream cheese, garlic powder, salt, and black pepper until well combined.
Spread an even layer of the cream cheese mixture over each tortilla, leaving a small border around the edges.
Evenly distribute the shredded carrots, cucumber slices, bell pepper slices, red onion, and spinach leaves over the cream cheese layer on each tortilla.
Starting from one end, carefully roll the tortilla tightly to enclose the filling. Repeat with the second tortilla.
Once rolled, use a sharp knife to slice each tortilla into 1-inch thick pinwheels.
Arrange the roll-ups on a serving platter and serve immediately, or refrigerate for 30 minutes to firm up before serving.
