David Bouley inspired me to make this recipe. A nice dish to impress your friend and family. It's very earthy. Comfort food! Truffles are very expensive but once in a while we deserve to enjoy things that God has given us! Olive oil can be used in place of the truffle oil. This can be a Vegetarian dish just sub the butter for oil or skip it. My DH once would never eat a mushroom now you can't keep it away from him.
