Prepare the corn bread mix according to package directions. Cool completely, then chop or crumble into a large bowl.
Preheat the oven to 350 degrees F. Spray a 1 to 2-quart baking dish with cooking spray; set aside.
In a skillet set over medium heat, melt the butter. Saute the celery and onion for 4-5 minutes, until softened.
Add the vegetables to the bowl with the cornbread. Sprinkle the seasonings over and toss to combine. Whisk the eggs into the chicken broth, then pour over the contents of the bowl, mixing gently until well combined.
Transfer to the prepared baking dish and bake for 25-30 minutes.
Notes
To make ahead of time, cook the stuffing as directed, store in the fridge covered tightly until needed, then reheat at 350 degrees F until warmed through.
