That's true to some extent.its a miracle when a verduleria stocks aji (chile peppers) . the silver lining about the shit food and selection here is that it allows you to simplify, or minimalize your diet because flavor isn't to be found tempting you.
you can eat a very healthy simply and cheap diet here by taking advantage of the local production.
beef, fruit, honey, wine, olive oil, leche (from which you can make your own greek yoghurt easily) if you require something else, you require too much,
In Uruguay, I couldnt stop scoffing down the blue cheese, olives and morcilla - not exactly the healthiest. Whereas, when I bought the same here, I was tempted because it had no taste.
