Heat oven to 400 degrees. Grease a 9-inch square baking pan or a 10-inch oven-proof skillet. (I used an iron skillet and poured 2 tablespoons peanut oil into the bottom and used my hands to spread it over the bottom and around the sides of the skillet. Then, I heated the skillet to a very high heat right before pouring the cornmeal batter in. Do not let the hot oil smoke!) In a large bowl, combine 2 cups self-rising cornmeal mix, 1 cup shredded Cheddar Cheese, 1 cup sour cream, 1 cup whole kernel corn, 4 oz. can drained green chiles, 2 well-beaten eggs, and 2 tablespoons vegetable oil. Stir, just until all ingredients are combined. Pour into a hot, greased skillet or baking pan. Bake for 20 minutes, or until golden brown and done. To test for doneness, place a toothpick in the center of the cornbread, and it should come out clean. Immediately remove from oven, and cut into pie-shaped wedges (for skillet) or squares (for baking pan). Serve piping hot with fresh butter! Delicious!!! You can serve this cornbread with Tex-Mex style chili, or a bowl of chili hot beans, or just eat it by itself with butter, along with a cold glass of milk! Its wonderful!!!
