Preheat your grill or a stovetop grill pan over medium-high heat to ensure a nice sear on the chicken.
In a mixing bowl, season the chicken breasts generously with Cajun seasoning, salt, and pepper, making sure each piece is evenly coated for maximum flavor.
Drizzle a bit of olive oil onto the grill or pan to prevent sticking, then carefully place the seasoned chicken on it. Cook for 6-7 minutes on each side, or until the chicken is cooked through and registers an internal temperature of 165°F (75°C).
After cooking, remove the chicken from the grill and let it rest for 3-5 minutes to lock in juices. Once rested, slice the chicken into thin strips for easy wrapping.
In a large mixing bowl, combine the chopped Romaine lettuce, Caesar dressing, and grated Parmesan cheese. Toss the ingredients together until the lettuce is well coated in dressing and cheese, creating a delicious salad mix.
Lay out each flour tortilla on a clean surface. Spoon an even amount of the Caesar salad mixture into the center of each tortilla, spreading it slightly for even distribution.
Layer the sliced Cajun chicken on top of the salad mixture and sprinkle with crushed croutons if you choose, adding a crunchy texture to the wraps.
Carefully fold in the sides of each tortilla, then roll it up tightly from the bottom to create a secure wrap.
Slice each wrap in half diagonally for easy eating, and arrange them on a serving platter. Garnish with a sprinkle of chopped parsley for a fresh touch.
