The classic version is served straight out of a slit-open single-serving Fritos bag, a serving method said to have started at the old Woolworth's counter on the Santa Fe Plaza.
Corn chips are topped with a scoop of chili, chopped onion, and shredded cheese and eaten with a plastic fork right out of the bag. Plaza vendors and fair stands across New Mexico still serve it this way.
