Steak Au Gratin

• 1/2 pound boneless sirloin steak
• 2 teaspoons butter
• 1 cup onions sliced
• 1 garlic clove minced
• 1/2 cup canned beef broth
• 1 tablespoon red wine vinegar
• 2 teaspoons dijon mustard
• 3 tablespoons dried bread crumbs plain
• 1 tablespoon fresh parsley each chopped
• grated Parmesan cheese

1. On rack in broiling pan broil steak until rare, 3 or 4 minutes on each side.
2. While steak is cooking, in 10 inch nonstick skillet heat butter over high heat until bubbly and hot; add onions and garlic and saute, stirring occasionally, until onions are tender-crisp, 2 to 3 minutes. Stir in broth, vinegar and mustard and continue cooking until liquid is reduced by half, 3 or 4 minutes longer.
3. Transfer steak to 9 x 9 x 2 inch flameproof baking dish and top with onion mixture. In small bowl combine bread crumbs, parsley, and cheese, mixing well. Sprinkle over onion mixture and broil until topping is lightly browned, 1 to 2 minutes.
