Re-worded from en.wikipedia.org/wiki/Focaccia
Focaccia is a flat bread topped with spices and other products, which is related to modern pizza. The basic recipe is thought by some to have originated with the Etruscans (early Romans) or ancient Greeks. It is quite popular in Italy where it is usually seasoned with olive oil and herbs, topped with cheese and meat or flavored with a number of vegetables. Focaccia doughs are similar in style and texture to pizza doughs consisting of high-gluten flour, oil, water, sugar, salt and yeast.
