Using garlic bread makes this sandwich super special!

1/2 pound sliced fresh mushrooms
2/3 cup sliced onion
4 tsp butter
1 tsp minced garlic
1 tsp Worcestershire sauce
1 pound shaved deli roast beef
6 slices Colby cheese
Bake garlic bread according to package directions. Meanwhile, in a large skillet, saute mushrooms and onion in butter until vegetables are tender. Add minced garlic, cook 1 minute longer. Stir in Worcestershire sauce.
Layer each half of garlic bread with roast beef, mushroom-mixture and cheese. Return to oven; bake a few minutes longer until cheese is melted. Slice and serve immediately.
