Grill the chicken breasts until fully cooked, about 6-8 minutes per side, then slice them into strips.
Mix in a bowl the chopped romaine lettuce and Caesar dressing, tossing gently to coat evenly.
Lay a tortilla flat and place a portion of the dressed romaine in the center.
Add sliced grilled chicken on top of the lettuce, followed by croutons and a sprinkle of Parmesan cheese.
Fold the sides of the tortilla inward, then roll it up tightly from the bottom to the top.
Cut the wraps in half and serve immediately, with extra Caesar dressing on the side if desired.
