Creating Roasted Red Pepper Mozzarella Stuffed Chicken is a simple process, and following these steps will help ensure your success:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). This will ensure that your chicken cooks evenly.
2. Prepare the Filling: In a mixing bowl, combine the chopped roasted red peppers, shredded mozzarella cheese, chopped spinach, minced garlic, Italian seasoning, salt, and black pepper. Mix well until all ingredients are thoroughly combined.
3. Prepare the Chicken Breasts: Using a sharp knife, slice a pocket into each chicken breast. Be careful not to cut all the way through.
4. Stuff the Chicken: Generously fill each chicken breast pocket with the roasted red pepper and mozzarella mixture. Use toothpicks to secure the openings if necessary.
5. Sear the Chicken: In a large oven-safe skillet, heat the olive oil over medium heat. Once hot, add the stuffed chicken breasts and sear them for about 3-4 minutes on each side, until golden brown.
6. Bake the Chicken: Transfer the skillet to the preheated oven and bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
7. Rest the Chicken: Once cooked, remove the skillet from the oven and let the chicken rest for 5 minutes before slicing. This helps retain the juices.
8. Garnish and Serve: Top the chicken with fresh basil leaves if desired, and serve warm.
