Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine the shredded chicken, uncooked rice, chicken broth, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper.
If using, stir in frozen peas and carrots.
Pour the mixture into a greased 9×13 inch baking dish.
Cover the dish with aluminum foil and bake for 45 minutes.
Remove the foil and sprinkle shredded mozzarella cheese on top. Bake uncovered for an additional 10-15 minutes until the cheese is melted and bubbly.
Garnish with fresh parsley if desired and serve hot.
