Follow these straightforward steps to create your Chicken Caesar Croissant Sandwich:

1. Cook the Chicken: If using raw chicken, season it with salt and pepper. Cook in a skillet over medium heat for about 6-8 minutes per side or until fully cooked. Let it cool before shredding or dicing.
2. Prepare Dressing: In a bowl, combine the cooked chicken with the Caesar dressing. Mix until the chicken is well coated.
3. Chop the Lettuce: In a separate bowl, add the chopped romaine lettuce and Parmesan cheese. Toss lightly to combine.
4. Slice Croissants: Carefully slice each croissant in half, creating a bun-like structure while keeping them attached on one side.
5. Assemble the Sandwich: On the bottom half of each croissant, add a generous amount of the chicken mixture. Top with a handful of the romaine and cheese mix.
6. Add Pepper: Lightly sprinkle freshly cracked black pepper over the top for added flavor.
7. Optional Toppings: If desired, add sliced tomatoes, bacon bits, or avocado to elevate your sandwich.
8. Close and Serve: Place the top half of the croissant back on. Press down gently and cut each sandwich in half for easier handling.

With these steps followed, you will have a delicious Chicken Caesar Croissant Sandwich ready to enjoy!
