Every year on the Saturday preceding the Super Bowl, Wild Oats Market in Albuquerque sponsors the Chef’s Invitational Souper Bowl Soup Contest. In 1995, W.C. defeated a dozen of other Albuquerque chefs with this grand prize winner. Use whatever wild mushrooms you have to make 9 ounces—we have suggested a mixture, below. W.C. gathered most of the musrooms from the Sandia Mountains near Albuquerque and urges aficionados to learn about wild mushrooms.
In Australia, we use a long loaf of Turkish bread for these sandwiches, but you can use Mexican bolillos or even Kaiser rolls. As you might expect, the sauce is the secret ingredient. The sandwiches can be assembled, wrapped in plastic wrap and refrigerated overnight for grilling the next day if desired.
