How to cook
Using a sharp knife, cut the fillet into very thin slices. Divide it into 4 plates.
The lemon juice is mixed with salt and pepper. Add the olive oil and pour the resulting dressing over the meat.
Cover it and let it marinate in a cool place for at least 10-15 minutes.
Put slices of parmesan next to the beef, sprinkle with parsley and garnish with lemon slices.
