Cicoria is chicory, usually sauteed in olive oil and garlic for a vegetable accompaniment to the main course, the contorno. In Rome, where the picture was taken, dried pepperoncino, hot pepper, is often added.
The pronunciation is like adding the ia at the end of the English “chicory” and moving the accent to the last syllable: like this
In the spring you might find wild cicoria, La cicoria selvatica.
