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.
Great tip, thanks for sharing.
Itś interesting how the fruit and vegetables availability changes from Argentina, Uruguay and Chile, even though they are so close to eachother and share many cultural ways.
