An easy appetizer for a party or gathering. No one will ever believe there are only three ingredients after experiencing the flavor punch. I leave the mushrooms whole rather than slicing them. Melt in your mouth delicious and will have people coming back for more! Easy, inexpensive, and everyone loves it. If you like, you can replace some of the butter with olive oil. I like to do half cremini and half white button mushrooms. From CD Kitchen.
