Pre heat oven to 400.
Brown breakfast sausage in a pan.
While it's browning, mince your onion, celery, and mushroom.
Once sausage is mostly cooked, add your minced veggies plus garlic and saute through.
In a separate bowl, add stuffing mix, salt, black pepper, sage, eggs, and chicken broth.
After sausage and veggies are fully cooked, add them to the bowl and mix thoroughly.

Butter the bottom of your pan, or use parchment paper or silicone baking mats.
