In a medium bowl, thoroughly combine shredded or chopped cooked chicken with Caesar dressing, grated Parmesan cheese, and chopped romaine lettuce. Toss well to coat evenly.

Lay a large flour tortilla flat on a clean surface. Spoon one-quarter of the chicken Caesar mixture down the center, arranging evenly.

Fold the sides of the tortilla inward, then tightly roll from the bottom to secure the filling.

Repeat the process with the remaining tortillas and chicken mixture. Cut in half diagonally for easier consumption.

Serve immediately on a platter or wrap in plastic wrap for later. If storing, keep in an airtight container in the refrigerator for up to 2 days.
