Creating Roasted Red Pepper, Spinach, and Mozzarella Stuffed Chicken can be a straightforward task if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking.

2. Prepare the Filling: In a medium bowl, combine the roasted red peppers, fresh spinach, mozzarella cheese, minced garlic, Italian seasoning, salt, and pepper. Mix well until all ingredients are evenly distributed.

3. Prepare the Chicken: Using a sharp knife, carefully cut a pocket into each chicken breast. Make sure not to cut all the way through; you want to create a pouch for the filling.

4. Stuff the Chicken: Generously fill each chicken breast pocket with the prepared mixture. Do not overfill, as it will be hard to close.

5. Secure the Stuffing: Use toothpicks or kitchen twine to secure the opening of each stuffed chicken breast, ensuring the filling stays intact during cooking.

6. Sear the Chicken: In a large skillet, heat the olive oil over medium-high heat. Add the stuffed chicken breasts and sear for about 3-4 minutes on each side until golden brown.

7. Transfer to the Oven: After searing, transfer the chicken to a baking dish. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and no longer pink in the center. The internal temperature should reach 165°F (75°C).

8. Rest and Serve: Once cooked, let the chicken rest for about 5 minutes before removing the toothpicks or twine. This allows the juices to redistribute throughout the meat.

9. Optional Garnish: If desired, sprinkle fresh herbs like parsley or basil on top for an enhanced presentation.

These straightforward steps will guide you in creating this incredible dish without any hassle.
