In the 20th century, pizza has become an international food. The toppings may be quite different depending on the local tastes. These pizzas consist of the same basic design. They also include many types of ingredients such as anchovies, egg, pineapple, banana, coconut, sauerkraut, eggplant, kimchi, lamb, couscous, chicken, fish, and shellfish. Sometimes, meats prepared in styles such as Greek lamb, Gyros or chicken tikka masala, and non-traditional spices such as curry and Thai sweet chili are added too. Pizzas can also be made without meat for vegetarians, and without cheese, for vegans.
