>>9714131We have more than tens of millions of people here so there's many regions of American ethnic foods. New England food, Southwestern, Cajun, Southern, Midwestern, Tejano (TexMex), different regional barbecue, etc. Hotdog, burgers and pizza are the most obvious ones across all places, but that's because they were brought in the 19th century wave of migration and spread to most cities, but every region has its own cuisine. Mac and cheese was apparently invented by Thomas Jefferson, so that has to be the most American food.
