Preheat the BBQ plate to medium heat. Drizzle with extra virgin olive oil and place the tomatoes, onion, apple slices, and jalapeños onto the plate. Cook until slightly charred and softened.
Transfer the grilled ingredients, along with the garlic, apple cider vinegar, coriander stems, and a pinch of salt, into a food processor. Pulse until roughly chopped and combined.
Spoon the salsa into a small serving bowl and serve with corn chips on the side.
