If not already cooked, grill the chicken breasts until fully cooked, about 6-7 minutes per side. Let cool and then shred or dice.

In a mixing bowl, combine the cooked chicken, chopped romaine lettuce, Caesar dressing, and grated Parmesan cheese. Toss until well coated.

Lay a tortilla flat and spoon a portion of the chicken mixture onto the center. Add croutons if desired.

Fold in the sides of the tortilla and roll it up tightly from the bottom. Repeat with remaining tortillas. Cut in half and serve immediately.
