Directions

1. In a small bowl combine panko, butter, horseradish, 2 tablespoons of the parsley, and Worcestershire. Season with salt and pepper to taste; set aside.
2. Coat grill rack with nonstick cooking spray. Preheat grill to high (400F to 450F). Season steaks with salt and pepper to taste. Grill 5 to 6 minutes; turn steaks. Spread a rounded 1/4 cup of the panko mixture on each steak; gently press to adhere. Grill 5 to 6 minutes more for medium-rare (145F), or to desired doneness.
3. Remove steaks from grill; let stand 2 to 3 minutes. Sprinkle with remaining 2 tablespoons parsley, and serve.
