Sarna (Bolivian tomato and onion salad)

Instructions

1. Wash the tomatoes, remove the seeds and cut them into small, even dice.
2. Thinly slice the red onion and rinse it under cold water for a minute to soften its bite, then drain it.
3. Deseed the chili and cut it into thin strips or small dice.
4. Roughly chop the coriander, keeping a few nice leaves for garnish.
5. In a bowl, mix the tomatoes, onion, chili and coriander.
6. Add the lime juice, oil, salt, pepper and cumin, then toss gently.
7. Let it rest for 10 minutes at room temperature so the flavours blend, then adjust the seasoning before serving.
