Preheat a large skillet over medium heat and add the olive oil.
Season the chicken breasts with garlic powder, onion powder, Italian seasoning, salt, and pepper.
Place the seasoned chicken in the skillet and cook for about 6-7 minutes on each side, or until fully cooked and no longer pink in the center.
Remove the chicken from the skillet and let it rest for a few minutes. Then, using two forks, shred the chicken into bite-sized pieces.
In a large bowl, combine the shredded chicken with the Caesar dressing, mixing well to coat.
Warm the tortillas in a dry skillet or microwave until pliable.
To assemble the tacos, place a generous amount of the chicken mixture on each tortilla. Top with chopped romaine lettuce and a sprinkle of grated Parmesan cheese.
Serve with lemon wedges on the side for an extra burst of flavor.
