Hawaiian pizza is a pizza which usually consists of a cheese and tomato base with pieces of ham and pineapple. Some versions include bacon, onions, green pepper, and/or jalapenos, but the version with ham and pineapple only is the most common. It is the most popular pizza in Australia, accounting for 15% of sales.
Despite its name, Hawaiian pizza is not a Hawaiian invention. In Italy, Hawaiian pizza is considered to be a German invention (or a German modification of Italian cuisine), similar to the Toast Hawaii.
