Brush one side of the sliced bread with butter, sprinkle with parmesan cheese and toast on a griddle for two min.
Cook the steak in a non stick pan for 4-5 min on each side. Combine the A-1 and beef broth together and a few shots while cooking each steak. Season with S+P. When the steaks are almost done place a slice of swiss cheese on top and allow it to melt completely.
Spread horseradish cream on each slice of bread then put two steaks per sandwich because it's that good.
