Hamburger variants refer to the many different styles and types of hamburgers that can be found around the world. While the classic hamburger consists of a ground beef patty served in a bun with various toppings, variants can include different meats like turkey, chicken, or plant-based options such as veggie burgers and impossible burgers. Toppings can also vary widely, featuring ingredients like bacon, cheese, avocado, and various sauces. Regional variations often highlight local flavors and ingredients. For example, the Hawaiian burger typically includes grilled pineapple and teriyaki sauce, while the California burger may feature fresh vegetables and avocado. These unique combinations allow for endless creativity in hamburger preparation and presentation.
