Creating this Spinach-Stuffed Chicken Breast with Mozzarella is as simple as it is delicious. Follow these step-by-step instructions to bring this dish to life:

1. Preheat the Oven:
   Preheat your oven to 375°F (190°C) to ensure it’s ready for baking once the chicken is prepared.
2. Prepare the Spinach Mixture:

   • Add the minced garlic and sauté until fragrant.
   • Toss in the chopped spinach and sauté until wilted.
   • Mix in the mozzarella cheese, salt, pepper, and Italian seasoning (if using). Stir until the cheese is melted and the mixture is well combined.
3. Stuff the Chicken Breasts:
   • Carefully cut a pocket into each chicken breast.
   • Stuff each pocket generously with the spinach and cheese mixture.
4. Prepare for Baking:
   • Place the stuffed chicken breasts in a baking dish.
   • Season the outside with salt and pepper.
5. Bake the Chicken:
   Bake the stuffed chicken breasts in the preheated oven for 25-30 minutes or until the chicken is fully cooked through and the juices run clear.
