Preheat your oven to 350°F. Grease a 13x9-inch pan, then dust it with 1 tablespoon of cornmeal for a delightful touch.
Combine cake mix, 1 1/3 cups cornmeal, sugar, and baking soda in a large bowl; mix thoroughly.
Combine sour cream, oil, and eggs in a small bowl. Pour mixture into cornmeal mixture and stir until well combined. Gently fold in sausage, cheese, and jalapeño chile. Transfer mixture into a pan and spread evenly.
Bake for 35 to 40 minutes until a toothpick inserted in the center comes out clean. Serve warm.
