Prepare the ingredients by washing and slicing the vegetables as needed.
Lay a tortilla flat on a clean surface.
Spread a generous layer of hummus over the tortilla, leaving a small border around the edges.
Begin layering the sliced bell peppers, cucumbers, shredded carrots, spinach, and red cabbage in the center of the tortilla.
If using, sprinkle feta cheese over the layered vegetables.
Drizzle with olive oil if desired and season with salt and pepper to taste.
Carefully fold the sides of the tortilla inwards, then roll from the bottom up to create a tight wrap.
Slice the wrap in half diagonally and serve immediately.
