Cut the Quartirolo cheese into small cubes and dress with oil, salt and chilli.
Clean and wash the celery and slice finely, peel the apple, cut into quarters and then cut into thin slices. Slice (following the fibre) the florets of the cauliflower and the radishes. Mix together the vegetables and dress with a citronette.
Add the cheese and the hazelnuts to the vegetables, delicately mix together and arrange the salad on a serving plate.
