Follow these steps to create your mouth-watering Primavera Stuffed Chicken:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: Using a sharp knife, slice a pocket into each chicken breast. Be careful not to cut all the way through.
3. Mix Filling: In a bowl, combine the diced bell peppers, zucchini, spinach, cream cheese, mozzarella, garlic, Italian seasoning, salt, and pepper.
4. Stuff Chicken: Spoon the filling into each chicken breast pocket. Use toothpicks to secure the opening if necessary.
5. Sear Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Sear the stuffed chicken breasts for 3-4 minutes on each side until golden brown.
6. Bake: Transfer the skillet to the preheated oven and bake for 25-30 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
7. Rest: Once cooked, remove the skillet from the oven and allow the chicken to rest for 5 minutes.
8. Serve: Garnish with fresh parsley if desired, and serve with your favorite side dishes.
