This simple recipe for a "gourmet's" salad comes from balsamic vinegar producer Acetaia Leonardi.
Clean and dry the radicchio and place it in a large salad bowl. Scatter with shavings of Parmigiano-Reggiano and hard-boiled eggs, cut into cubes. Season with a drizzle of olive oil, balsamic vinegar and salt, to taste. Toss well. Top with bacon.
