I'm going to tinker with the recipe a bit, I think. But here's the basics:
Mushrooms (pizza guy said they slice theirs in quarters so they are nice and thick)
Dry red wine
Salt, to taste
Melt the butter and add the quartered mushrooms. Sautee slowly over low heat until brown. Add wine, stir, and let continue to simmer over low until liquid is cooked into the mushrooms. Season with oregano, salt and pepper.
