Herrings, oranges and olives salad

The herrings, orange and olives salad is a poor dish of the Sicilian cuisine. Oranges could be found everywhere, and the coast of Palermo was called Conca d’Oro because of the multitude of orange trees full of golden fruits; the herrings are a blue fish, never particularly valued by the markets (fortunately) and therefore of low cost and easy to get for everyone, despite the great nutritional value of its meat.
