This one is pretty basic.....
8 oz mushrooms
1/2 small diced onion
2 cloves garlic
t thyme
1/2 cup dry red wine
1 cup beef broth
Sautee mushrooms and onion in butter, add garlic when liquid is almost gone for about 30 seconds, when liquid has dried up deglaze with red wine, add beef broth and simmer for about 10 minutes. Done deal, scoop out the mushrooms for the sandwiches and dip away.
