Preheat oven to 375 degrees F. Brown meat in a medium-sized sauce pan over medium-high heat. In a separate bowl combine cornmeal, cream-style corn, salt, soda, milk, green chiles and egg. Blend well. Pour one half of the cornmeal mixture into a cast iron skillet. Layer ground meat, onions, cheese and peppers on top. Pour remaining cornmeal over layers. Place in oven and bake until golden brown, approximately 45 minutes.
