Ensalada chilena is quite popular in chile, probably because it's so simple to make and goes well with many different things. This salad is similar in appearance and preparation to the peruvian salad salsa criolla, except that the chilean version has tomatoes. Like salsa criolla, the onions should be thinly sliced "A la pluma" Style (like feathers), and soaked in salt water for a bit to soften their intense flavor and sweeten them. Serve ensalada chilena alongside grilled meats, empanadas, or milanesas with rice. Diced avocado makes a nice addition to this salad.
