Wash the fennel, dry it well, cut it into quarters and slice it finely with the truffle cutter in a salad bowl.
Wash the red radicchio veronese, dry it and cut it into thin strips and add it to the fennel.
Season with salt, drizzle with oil and vinegar, stir, and serve.
Notes
For a touch of originality and a hint of sweetness, you can add green apple slices or chopped walnuts. This will not only enrich the flavor but also add a nice crunch to your salad.
