In a food processor, pulse the onion, tomato, chilli and most of the coriander until finely chopped (or you can do this by hand), then transfer to a bowl.

Roll the lime over the work surface with some pressure to help juicing, then cut in half, juice it and add to the mix.

Now cut your avocados in half, remove the stone and scoop out the creamy flesh with a spoon, making sure you get all the lovely bright green bit close to the skin.

With clean hands squash the avocado to a pulp to make it super creamy. Leave a few of the chunks for a bit of texture. Mix through the blitzed veg and some seasoning. Serve immediately with a drizzle of good olive oil over the top and some more coriander.
