While the mushrooms are cooking get started on the stuffing. In a small skillet melt the butter over med high heat and add the mushrooms and shallot along with the rosemary and sage and saute until they become soft. Add the stuffing mix and just enough chicken broth to moisten it up. Somewhere between and 1/4 and 1/2 cup should do it. Spray a muffin time with cooking spray and fill with the stuffing. Bake 400 degrees for 20 minutes until golden brown and crunchy.
