I suppose the classic way is to beat it out with a meat mallet or rolling pin, egg and breadcrumb it and shallow fry in a tablespoon of olive oil (not extra virgin) and a knob of butter over a medium heat until golden brown. Serve with sauté potatoes and spinach and a squeeze of lemon juice. Not the healthiest of recipes, I know, but once in a blue moon won't do you any harm.
Alternatively, pan fry the escalop in the tiniest amount of oil and then add a tomato sauce/ragu and simmer for 15 mins. Serve either with boiled potatoes and steamed green beans or with tagiatelli. And a nice bottle of Italian red!
