Grilled Pepper Sirloin Steak

Ingredients

1 (2-1/2 pound) sirloin steak, 1-1/2 inch thick 
1/2 cup (125 ml) butter or margarine 
1/4 cup (60 ml) chopped fresh parsley or 4 tsp (20 ml) dried parsley 
1/4 cup (60 ml) minced onion 
2 tbsp (30 ml) worcestershire sauce 
1 tsp (5 ml) freshly ground pepper 
1/2 tsp (2 ml) dry mustard 

Instructions

Preheat grill or broiler. Lightly score edges of steak at 1 inch intervals, to prevent curling. Combine butter, parsley, onion, worcestershire sauce, pepper and mustard in a small saucepan. Heat, stirring continually, over low heat, until butter melts. Reserve 1/4 of the mixture. Place steak on grill or broiler pan. Brush steak with the butter mixture. Cook, basting frequently with the butter mixture, about 6 to 8 minutes per side depending how you like your steaks done. Place steak on a serving platter. Cut thin slices across the grain of the steak. Drizzle reseved butter mixture over steak.
