Grill or sauté the chicken until fully cooked, then shred or dice it.

In a mixing bowl, combine the cooked chicken, romaine lettuce, cherry tomatoes, red onion, and Caesar dressing. Toss until well coated.

Lay a tortilla flat and place a portion of the chicken mixture in the center. Sprinkle with Parmesan cheese.

Fold in the sides of the tortilla and roll it up tightly from the bottom.

Cut the wraps in half and serve immediately, or wrap in foil for later.
