Cook the washed potatoes in salted boiling water. When cool enough to handle, peel and slice thinly. Drizzle with a little walnut oil, season then cover and keep warm.
In a pan, gently fry the lardons with a smear of olive oil. The lardons should
be crispy but not dry, add a few drops of vinegar and pour all of this into the potatoes.
Dress the well-washed salad with a little walnut oil, vinegar, salt and pepper. Add the shallots and then the warm potato mix.
Finally, sprinkle over shavings of the cheese. Serve warm.
