In a mixing bowl, combine the shredded chicken, chopped romaine lettuce, Caesar dressing, grated parmesan cheese, and black pepper. Mix well until everything is evenly coated.

Taste and adjust seasoning if necessary, adding more dressing or pepper to your liking.

Slice each croissant in half horizontally.

Spoon a generous amount of the Chicken Caesar salad mixture onto the bottom half of each croissant.

If desired, top with halved cherry tomatoes and crispy bacon bits.

Place the top half of the croissant back on and press gently.

Arrange the sandwiches on a serving platter and serve immediately.
