What is "chacarero"

Chacarero is a Chilean sandwich made with thinly sliced churrasco-style steak, or lomito-style pork on a round roll with tomatoes, green beans and chili pepper.

It is one of the many varieties of sandwich served in Chilean fuentes de soda, or schoperías, restaurants equivalent to the British concept of a greasy spoon, that serve fast food and draught beer.

It was considered by Time magazine as one of "The 13 Most Amazing Sandwiches the World Has to Offer".
