Santas Garnachas takes viewers into the world of Mexican street food, with attention to the people who prepare the food and to the critical gourmets. The dish that is central to the series is Garnacha. In this dish, a corn tortilla is generously garnished, for example with beans, (grated) cheese, onions and/or chili peppers. The dish comes from the Oaxaxa region, and is very popular on street corners and markets.
