1 1/2 pounds beef sirloin steak
8 cups romaine lettuce, torn into bite-size pieces
6 roma (plum) tomatoes, sliced
1/2 cup sliced fresh mushrooms
3/4 cup crumbled blue cheese

1/3 cup vegetable oil
3 tablespoons red wine vinegar
2 tablespoons lemon juice
1/2 teaspoon salt
1/8 teaspoon ground black pepper
3 teaspoons Worcestershire sauce
1/8 teaspoon liquid smoke flavoring
Preheat oven on broiler setting. Broil steaks for 3 to 5 minutes per side, or to desired doneness. Allow to cool, then slice into bite-size pieces.
On chilled plates, arrange lettuce, tomatoes, and mushrooms. Sprinkle with blue cheese and walnuts. Top with steak slices.
In a small bowl, whisk together oil, vinegar, lemon juice, salt, pepper, Worcestershire sauce, and smoke flavoring. Drizzle over salad.
