Creating Savory Stuffed Chicken with Roasted Red Peppers, Spinach, and Mozzarella is simple if you follow these clear steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare Chicken: Place each chicken breast between two sheets of plastic wrap. Using a meat mallet, pound the chicken to about 1/2-inch thickness.
3. Season Chicken: Sprinkle salt, pepper, and Italian seasoning over both sides of the chicken breasts.
4. Sauté Vegetables: In a skillet over medium heat, add olive oil. Once hot, add minced garlic and sauté for 30 seconds. Add chopped spinach and roasted red peppers. Cook until the spinach wilts, about 2-3 minutes.
5. Add Cheese: Remove the skillet from heat. Stir in the shredded mozzarella cheese until well combined.
6. Stuff Chicken: Place equal amounts of the spinach and pepper mixture in the center of each chicken breast. Fold the chicken over to enclose the filling, securing with toothpicks if necessary.
7. Transfer to Baking Dish: Arrange the stuffed chicken breasts in a lightly greased baking dish.
8. Bake: Bake in the preheated oven for 35-40 minutes, or until the chicken is cooked through and juices run clear.
9. Rest: Remove the chicken from the oven and let it rest for about 5 minutes before serving.
10. Garnish: Optionally, garnish with freshly chopped basil for an added touch of flavor.

Following these simple steps will guide you in creating this incredible dish with ease.
