Make no mistake, this steak sandwich is the one!
1 sirloin steak, trimmed of fat
1 baguette, sliced in half lengthways
1 big handful of watercress
Salt and pepper
Knob of butter
2 tablespoons creamed horseradish
2 tablespoons mayonnaise
Get your frying pan nice and hot, oil up your steak, then cook for 2/3 minutes each side, leave to rest and slice thinly, tumble onto your baguette that's filled with rocket, drizzle over salt and pepper and horseradish mayonnaise.
