While the classic Hawaiian pizza features pineapple and Canadian bacon, there are numerous variations and regional twists on this beloved pizza. Some versions may include additional toppings like bell peppers, onions, or jalapeños, while others may substitute the Canadian bacon for other types of smoked or cured meats. In certain regions, the pizza may be topped with local or seasonal ingredients, such as fresh mango, roasted red peppers, or even grilled chicken.
