Marya made this lovely shrimp scampi on red quinoa with both oyster and lobster mushrooms.
The recipe came from the Carb Conscious Vegetaran by Robin Robertson. Marya took liberties with the recipe and added the lobster mushrooms.
And from the Jan-Feb 2009 issue of Veg News came this Clam-Free Chowder:
The primary ingredient is oyster mushrooms. As a former aficionado of the clam chowder, I'm convinced this would fool any omnivore.
