I wasn't exactly sure what to expected when I crossed the border from Argentina to Chile, but I was very happy (and surprised) to find people around the city selling vegan soy burgers out of large tupperware bins. The first time I saw this, right outside the Bellas Artes Metro station, I asked the guy several times if he was SURE it didn't contain any meat. After that, I ate at least one every day. One time the lady who sold me one asked me if I'd like some vegan potato mayonnaise. Awesome! Burgers cost 500 CLP, or about $1 USD.

Chile is also known for its excellent fruits. Head over to La Vega market in Santiago, about 5 blocks north of Plaza de Armas for a cultural experience and a huge selection of fruits, nuts, vegetables, and everything else for really cheap.
