Sicilian pizza
Sicilian pizza is pizza prepared in a manner that originated in Sicily, Italy. Sicilian pizza is also known as "sfincione" or focaccia with toppings. In the United States, the phrase "Sicilian pizza" is often synonymous with thick-crust pizza derived from the Sicilian "sfincione" .This type of pizza became a popular dish in western Sicily by the mid-19th century and was the type of pizza usually consumed in Sicily until the 1860s. The version with tomatoes was not available prior to the 17th century.
It eventually reached North America in a slightly altered form, with thicker crust and a rectangular shape.
Traditional Sicilian pizza is often thick crusted and rectangular, but also round and similar to the Neapolitan pizza. It is often topped with onions, anchovies, tomatoes, herbs and strong cheese such as caciocavallo and toma. Other versions do not include cheese. 
The Sicilian methods of making pizza are linked to local culture and country traditions, so there are differences in preparing pizza even among the Sicilian regions of Palermo, Catania
