1. Prepare the breadcrumbs:
2. On a wooden cutting board, break the biscottes (2 or 3 to start) into small pieces, then crush the pieces using a glass bottle by rolling it over them while applying pressure.
3. Beat the egg in a soup plate.
4. Spread the flour on another plate.
5. Take an escalope, coat it (on both sides) in flour, dip it in the egg, then lay it on one side in the breadcrumbs.
6. To ensure the breadcrumbs stick well to the escalope, press on it with the palm of your hand. Do the same for the other side of the escalope.
7. Repeat the same process for the other escalopes, and make the breadcrumbs as you need them.
8. Heat a frying pan over high heat with a drizzle of olive oil.
9. When the oil is hot, cook the escalopes for a few minutes on each side.
10. Season with salt and pepper to taste, and serve with a drizzle of lemon juice.
