1. 1. Prepare the Chicken Mixture: In a medium bowl, combine the shredded or diced cooked chicken with the Caesar dressing, grated Parmesan cheese, fresh lemon juice, and black pepper. Stir everything together until the chicken is evenly coated. The mixture should look creamy and well-seasoned.

2. 2. Warm the Tortillas (Optional but Recommended): Lightly warm each flour tortilla in a dry skillet over medium heat for about 15-20 seconds per side, or microwave for 10-15 seconds. This makes them more pliable and less likely to crack when rolled.

3. 3. Lay Out the Tortillas: Place a warmed tortilla on a clean, flat surface.

4. 4. Add the Lettuce: Arrange about 1/2 cup of chopped romaine lettuce in a line down the center of each tortilla, leaving about an inch free on the top and bottom edges.

5. 5. Spoon on the Chicken: Spoon a quarter of the chicken mixture over the lettuce on each tortilla.

6. 6. Sprinkle with Croutons: If using, sprinkle a small amount of crushed croutons over the chicken mixture for added crunch.

7. 7. Fold and Roll: Fold in the sides of the tortilla over the filling, then tightly roll the tortilla from the bottom up. Ensure it’s snug to keep the filling secure.

8. 8. Serve Immediately: Slice each wrap in half diagonally for easier eating and serve right away.
