Sauté the onion, peppers and celery in a skillet over medium heat until softened, about 5-6 minutes.
In a large mixing bowl combine the cooked rice, turkey, sautéed vegetables, peas and carrots. Mix in the cream of chicken, sour cream and half of the shredded cheese.
Spoon the mixture into a greased 9x13 casserole dish and top with the remaining shredded cheese.
Bake 25-30 minutes until heated through.
