Place the bresaola slices on a plate, spread over the rocket and the pickled porcini mushrooms. Marinate with olive oil (in which the mushrooms are pickled) and a few drops of lemon juice. Salt and pepper to taste. Sprinkle with grated grana (or parmesan).
A Panino di Segale, a rye roll, tastes good with it.
Bresaola is salted and air-dried beef, a specialty from the Valtellina. The small parts are called Slinzeghe. A similar product is the so-called Bündner Fleisch from Switzerland, with which this starter can be prepared in exactly the same way.
