Clean and wash the Roman broccoli thoroughly. Steam the florets for about 10 minutes: they should remain crunchy. Transfer them to a bowl and let them cool down. Add the mixed pickled vegetables cut into small pieces and the green and black olives. Season with four tablespoons of extra-virgin olive oil and two tablespoons of white wine vinegar. Cover with film and let it rest for two hours in a cool place. Lastly, add the strong Provolone Valpadana P.D.O. cut into large flakes, toss once again and serve.
