Recipe second for 4 people based on Pig - cooking method oven.
Preparation: Open the fillet like a book by making a deep incision along the length and flatten it with a meat tenderizer. Salt it lightly. Prepare the omelette: cut the onion into thin slices and brown it in a spoonful of oil. Beat 4 eggs, add salt and pepper as required and the Parmesan to taste. Add the onion to the mixture and mix everything together. Cook the omelette. When the omelette is ready, place it on the fillet: at this point roll it up. Roll out the puff pastry and place the fillet in the centre: make a roll, trying to squeeze the sides of the pastry tightly, so that it does not open during cooking. Use the remaining egg yolk to brush the surface of the puff pastry. Bake in a preheated oven at 180 degrees for 45 minutes keeping the fillet covered for the first 35 minutes.
