[2][3] It is a sandwich of sliced beefsteak (churrasco), mozzarella, ham, tomatoes, mayonnaise and black or green olives.

A chivito commonly also includes bacon and fried or hard-boiled eggs.

[6][7] In Argentine cuisine a similar sandwich is called lomito.

In neighboring Argentina, chivito, barbecued kid, is a popular asado dish; it is reported that the Uruguayan chivito arose in Punta del Este, Uruguay, at a restaurant called "El Mejillón Bar" in 1946, when a woman[8][9][10] from northern Argentina or Chile ordered a sandwich of chivito for a hurried meal, expecting kid.

[1] The restaurant owner, Antonio Carbonaro,[11] did not have this meat and used beef fillet steak instead.
