Beef:
Wrap the beef tenderloin in a cling film and chill in the freezer for 2 hours until it is slightly hardened
Use a very sharp knife, cut the beef across the grain into thin slices
Place the beef slices between sheets of cling film and gently roll with a rolling pin until the beef is paper-thin
Arrange the beef slices on a plate
Arugula :
Add the arugula to a bowl and toss with 1 tablespoon of extra virgin olive oil, season with salt and pepper
Arrange the arugula in the center of the beef slices on the plate
Drizzle another tablespoon of extra virgin olive oil and pesto oil (optional) around the plate
Add the truffle paste around (optional), sprinkle with salt and freshly grated black pepper to taste
Top with the shaved Parmesan Cheese, serve immediately
