Stuffed Mushroom from Lemonade Making Mama

All it is... (are you ready?) mushrooms cleaned and stems gently pulled out... then simply spread or pipe room-temperature, Herbed Boursin cheese into the mushroom cavity. (I get mine at Costco but most grocery stores carry it.)  Place mushrooms into baking dish and bake at 350, for 15-20 minutes until cheese is browning and mushrooms are tender.  Time varies depending on size of mushrooms.  Serve warm.  They go fast as well. Simple.
