Add to bowl with vegetables and stir to combine.In a large bowl, whisk together cornmeal, flour, baking powder, baking soda and remaining 1/4 tsp salt. In a medium bowl, whisk egg. Add buttermilk and honey and whisk until combined. Add to cornmeal mixture and stir gently until dry ingredients are moistened. Stir in butter.Mist a 9-inch pie plate with cooking spray. Spread about a third of cornmeal batter over the bottom of plate. Add beef mixture. Evenly pour remaining batter over top and sprinkle with cheese.
