1Preheat sandwich press.
2Butter all bread slices and sprinkle with parmesan. Place half slices on sandwich press, buttered-side- down.
3Layer with corned beef, sauerkraut and cheddar. Spread unbuttered side of remaining bread slices with mustard. Sandwich together, buttered-side-up and close sandwich press.
4Cook 4-5 mins until cheese melts and bread is well toasted. Add fresh rocket to each sandwich. Serve with pickles.
TIP: If you don't have a sandwich press, pan-fry in a large non-sticky frying pan, about 3 mins on each side.
