Place the beef tenderloin in between two pieces of plastic wrap and use the meat tenderizer/mallet to gently pound the meat until it is very thin.
Remove the plastic wrap and season the beef with salt and pepper on both sides.
Place the beef on a cutting board and use a sharp knife to thinly slice it crosswise into even pieces.
On a serving plate, arrange the beef slices in a single layer.
Drizzle the olive oil and lemon juice over the beef slices.
Top with arugula and Parmesan shavings.
Serve immediately and enjoy!
