Chili and hot dogs are one of those combinations that seem like they should have always been together. Both are now considered to be classically American foods, but they originate from drastically different cultures. Chili comes from similar recipes served in Latin American countries and hot dogs come from sausages brought to the states by German immigrants. So chili and hot dogs both came a long way to be united in perfect harmony and I think we can all agree it was worth it. Celebrate chili dogs on Chili Dog Day, which is celebrated on the last Thursday of July.
