What You'll Need
- 6 tablespoons (3/4 stick) butter
- 3 onions, thinly sliced

- 1/4 cup bottled steak sauce
- 1 loaf French bread, cut in half lengthwise
- 1 (8-ounce) package sliced provolone cheese
What to Do
- In a large skillet over medium-high heat, melt butter. Saute onions 8 to 10 minutes, or until they begin to turn golden. Remove to a bowl.
- Add mushrooms to skillet, reduce heat to medium, and cook 3 to 5 minutes or until softened, turning once. Return onions to skillet, add steak sauce, and stir.
- Preheat oven to broil. Divide mushroom mixture evenly over bread halves, top with cheese, and place on baking sheet.
- Broil 4 to 5 minutes, or until cheese is melted and top is golden. Use a serrated knife to cut diagonally into 6 equal servings and serve immediately.
