Preheat your oven to 350°F. Cook the chicken breast if it's not already prepared, then dice or shred it.

In a small bowl or measuring cup, mix 1 cup of water with 1 packet of chicken gravy mix, add 1/2 cup of chicken broth, and season with salt and pepper to taste, stirring until well combined.

In a large mixing bowl, combine the cooked chicken, frozen cauliflower rice, finely diced red onion, chopped green apple, frozen sweet potato, dried cranberries, shredded cheddar cheese, uncooked instant white rice, and the prepared sauce, mixing everything together until evenly distributed.

Transfer the mixture to a greased 9x13-inch baking dish and spread it out evenly. Bake at 350°F for 40-45 minutes, or until the edges are golden brown and the dish is heated through.

Let it cool slightly before serving, and store any leftovers in an airtight container in the refrigerator. Reheat individual portions in the microwave as needed.
