01 - Place a grill pan or skillet over medium-high heat and allow it to preheat while preparing the chicken.
02 - Brush both sides of chicken breasts with olive oil. Season evenly with salt, black pepper, and garlic powder, pressing the seasoning into the meat.
03 - Cook chicken for 6-7 minutes per side until fully cooked through, reaching an internal temperature of 165°F. Transfer to a cutting board and let rest for 5 minutes before slicing into thin strips.
04 - In a large mixing bowl, combine chopped romaine lettuce with Caesar dressing. Toss thoroughly to coat all leaves. Add cherry tomatoes and red onion if desired.
05 - Lay each tortilla flat on a clean work surface. Divide dressed lettuce evenly among the 4 tortillas. Top each with sliced grilled chicken and sprinkle with Parmesan cheese.
06 - Add freshly ground black pepper over each wrap according to personal preference.
07 - Fold in both sides of each tortilla, then roll tightly from the bottom to form a secure cylinder. Ensure the filling is evenly distributed.
08 - Cut each wrap diagonally in half and serve immediately. For portability, wrap tightly in aluminum foil to maintain freshness.
