Steak with Coffee Barbecue Sauce

1 beef top round steak, cut 3/4 inch thick

Sauce:
1 tablespoon vegetable oil
1 small onion, finely chopped
1/2 cup strong brewed coffee
1/2 cup catsup
1/2 cup Worcestershire sauce
1 tablespoon cider vinegar
1 tablespoon packed brown sugar
1/4 teaspoon pepper

In medium saucepan, heat oil over medium heat. Add onions; cook 3 to 4 minutes or until tender. Stir in remaining sauce ingredients. Bring to a boil. Reduce heat to low; simmer 15 minutes, stirring occasionally. Cool.

Place beef steak and 1/2 cup sauce in shallow dish; turn to coat. Cover; refrigerate 6 to 8 hours (or overnight, if desired). Cover and refrigerate remaining sauce.

Remove steak from marinade; discard marinade. Grill steaks, uncovered, 12 to 13 minutes for medium rare to medium doneness, turning occasionally.

Meanwhile, place reserved sauce in 1-cup glass measure. Microwave on HIGH for 1 to 1 1/2 minutes or until hot.

Carve steak into thin slices; serve with sauce.
