In a large skillet, add ground chicken and cook over medium heat, while breaking up chicken into small pieces. Cook until chicken is cooked through, about 10 minutes. Drain excess fat and add chicken to a 13" x 9" casserole dish. Add the remaining ingredients to the casserole dish (except cornbread topping), stir well. Make sure the mixture is evenly distributed.
In a medium bowl, combine cornmeal, baking powder, soda and salt. Add egg and buttermilk, stir just until combined. Spread batter evenly over the mixture, sprinkle with 1/4 cup cheese and bake until cornbread is golden and casserole is heated through, approximately 25-30 minutes.
