The Completo Italiano’s tomatoes, avocado, and mayonnaise resemble the colors of the Italian flag. The red tomato, white mayonnaise, and green avocado create the visual sequence associated with Italy’s tricolore.
The Completo Italiano is a Chilean hot-dog variation, usually served in a soft bun with a sausage and these three toppings. “Italiano” means “Italian” in Spanish, and the name refers to the appearance of the finished sandwich, not to an Italian origin.
The completo developed in Chile in the 1920s after Eduardo Bahamondes introduced the hot dog to Santiago. Chilean diners found the original version too plain, so toppings such as tomato and avocado became central to local preparations.
A common mix-up is confusing the Italiano with the standard completo, which may include sauerkraut, salsa Americana, or other condiments. The Italiano is specifically identified by its tomato, avocado, and mayonnaise combination.
