Lengua a la vinagreta

Lengua a la vinagreta is a cold appetizer that is popular in Uruguay and Argentina. It consists of boiled ox or beef tongue that is sliced into thin pieces, then marinated in a combination of white wine vinegar, olive oil, garlic, and parsley, while capers and hard-boiled eggs are used sometimes, but not always. Although lengua a la vinagreta is usually served as an appetizer, it also makes for a light lunch or dinner. It is recommended to serve the dish with a glass of red wine on the side.
