Preheat the oven to 350 degrees.
Prepare a casserole dish by spraying lightly with non-stick spray.
Place the cornbread mix in a large bowl and break up any lumps.
Add all of the other ingredients and stir well to combine.
Pour the batter into the prepared casserole dish and bake at 350 degrees for 45 minutes or until set (but not firm like cornbread) and lightly browned.
Optional: turn on the broiler for the last few minutes of baking to get the top of the casserole a little extra crispy.
