In the past this land was rich of livestocks and of cultivations: vineyards, almond orchards and olive-groves, that suited well for the rocky ground and often poor of water. Over these crops destined to the commerce, the farmers planted vegetables and onions, that were at the base of their feeding. For this in the local tradition there are a lot of culinary expressions for the onion. Above all in this dish the onion is sweetened thanks to vinegar and the long cooking in the oven. A pleasant side dish that mixes its genuineness and its taste..
