Making Chicken Parmesan Grilled Cheese is a straightforward process. Follow these steps to create this delicious meal:

1. Prepare Ingredients: Gather all your ingredients. Make sure your chicken is cooked and shredded or sliced.

2. Heat Pan: Preheat a skillet over medium heat. Add olive oil to the pan.

3. Assemble Sandwich: Take one slice of bread and layer half of the mozzarella cheese, followed by the chicken, marinara sauce, and sprinkle the Parmesan cheese. Add any desired Italian seasoning.

4. Add More Cheese: Top the chicken and sauce with the remaining mozzarella cheese. Finally, place the second slice of bread on top.

5. Cook Sandwich: Place the assembled sandwich in the skillet. Cook for about 3-4 minutes until the bread is golden brown.

6. Flip and Cook: Carefully flip the sandwich over and cook for another 3-4 minutes. The cheese should be melted, and both sides crisp.

7. Check Doneness: Ensure that the sandwich is nicely browned and the cheese is gooey.

8. Rest the Sandwich: Remove the sandwich from the pan and let it sit for a minute. This will help the cheese set slightly for easier cutting.

9. Slice and Serve: Cut the sandwich in half and, if desired, garnish with fresh basil.

10. Enjoy!: Serve hot and enjoy the delicious flavors of Chicken Parmesan Grilled Cheese.
