Cook the crispy chicken according to package directions or your homemade recipe until hot and crunchy.
Let the chicken rest for 2 minutes, then slice it into strips.
Add chopped romaine lettuce to a large bowl.
Add Caesar dressing, Parmesan cheese, lemon juice, black pepper, and a small pinch of salt if needed.
Toss gently until the lettuce is lightly coated.
Warm the tortillas for a few seconds so they are soft and easy to roll.
Place the Caesar lettuce mixture down the center of each tortilla.
Add sliced crispy chicken and a few croutons on top.
Fold in the sides of the tortilla, then roll tightly from the bottom.
Place seam side down, slice in half, and serve immediately.
