In a large bowl, combine the shredded chicken, Caesar dressing, Parmesan cheese, garlic powder, black pepper, and salt. Mix well until the chicken is evenly coated.
Heat a skillet over medium heat. Add the chicken mixture and cook for about 5-7 minutes, stirring occasionally, until heated through.
While the chicken is heating, warm the flour tortillas in a separate skillet or microwave until pliable.
To assemble the tacos, place a generous scoop of the chicken mixture onto each tortilla. Top with chopped romaine lettuce, cherry tomatoes, and croutons if using.
Garnish with fresh parsley and serve immediately.
