What food is only in America?

One iconic food that is primarily associated with America is the hamburger. While variations of ground meat patties exist globally, the hamburger as we know it, typically served in a bun with toppings like lettuce, tomato, and cheese, was popularized in the United States. Another example is the classic American barbecue, which features regional styles and unique sauces that are distinctly American. These foods reflect the country's diverse culinary landscape and cultural influences.
