Scrub the beets clean, reserving any nice leaves, then finely slice into matchsticks with good knife skills or using the julienne cutter on a mandolin (use the guard!).
Dress with ½ a tablespoon each of extra virgin olive oil and red wine vinegar, the horseradish and crème fraîche, then season to perfection with sea salt and black pepper.
Delicately toss with the watercress and any reserved beet leaves.
Divide up the bresaola between your plates, followed by the beet salad, then drizzle with 1 teaspoon of extra virgin olive oil, and serve.
