Preheat oven to 350 degrees F.
Place butter in a large skillet over medium heat.
Stir in diced celery and onion. Cook for 4-5 minutes or until it starts to soften.
Stir in poultry seasoning, stuffing mix, and chicken broth. Stir to combine. (If your skillet isn't large enough you can combine everything in a large bowl.)
Lightly spray a baking dish with non-stick cooking spray.
Place stuffing mixture into the dish.
Bake for 20-25 minutes or until heated through.
