Preheat oven to 400 F.
Beat the egg in large bowl.
Add the milk, oil, cornbread mix, and Creole seasoning and stir until smooth, like a pancake batter.
Stir in the remaining ingredients except the sauce.
Pour mixture into a 8-9" cast iron skillet and spread out evenly with a spatula.
Bake 20-30 minutes or until the cornbread is done and is golden brown.
Serve with warm sauce for dipping or drizzle the sauce over top.
