Hawaiian pizza is a pizza that usually consists of a cheese and tomato base with pieces of ham and pineapple. Often versions will have mixed peppers, mushrooms and bacon. Another variety consists of pineapple and Canadian bacon or American Bacon. It is the most popular pizza in Australia, accounting for 15% of pizza sales. 
Despite its name, Hawaiian pizza is not a Hawaiian invention but Canadian. The Village Voice, National Post, Toronto Sun, London Free Press and The Chatham Daily News have covered Sam Panopoulos' claim that he created the first Hawaiian pizza at the Satellite Restaurant in Chatham, Ontario, Canada in 1962. A co-owner of the Satellite Restaurant at that time - along with his brother, Nick Panopoulos - Sam and his brother were business partners for approximately 50 years. The brothers would later build on the popularity of the Hawaiian Pizza and begin serving their next creation - the Hawaiian Burger.
