• 1 cup beef broth
• 3 tablespoons whipping cream (unwhipped)

1. Butter each large half of the bread then, the place under the broiler for a couple of minutes to brown lightly or until slightly crisp.
2. In a large skillet cook the onions in the butter and oil over medium heat, stirring occasionally until the onions are crisp and golden, season with salt and black pepper; transfer to a paper towel using a slotted spoon.
3. Add in more butter and/or oil to the skillet if desired and add in the sliced mushrooms and garlic; saute until the mushrooms loose their moisture and are lightly browned; transfer mushroom/garlic mixture to a bowl.
4. To the same skillet add in the beef broth, Worcestershire sauce and black pepper, stirring with a wooden spoon to deglaze the skillet, scraping up any browned bits from bottom of the skillet.
