Urban Naturalist - Cornbread

Here's my cornbread recipe, as promised:

1/2 C cornmeal

1/2 C polenta

1 C whole wheat flour or kamut flour

4 teaspoons baking powder

1 egg, beaten

Heat oven to 400 degrees. Pour oil in cast iron skillet and heat in the oven. Tilt skillet to coat evenly with oil. Combine dry ingredients. Add hot oil, milk and egg. Mix. Stir in green chilies or corn if using. Pour batter into hot skillet. Bake 20-25 minutes or till golden brown.
