Burger patties are flat, round pieces of ground meat, typically made from beef, that are cooked and served in a burger. They are a key component of many popular fast food meals and can also be made from other proteins like chicken, turkey, or plant-based ingredients for vegetarian options. The preparation of burger patties involves seasoning the meat and shaping it into a uniform size for even cooking. They are usually grilled, pan-fried, or broiled, and can be served on a bun with various toppings such as lettuce, tomato, cheese, and condiments like ketchup and mustard.
