Slice the tomatoes and avocados into wedges and transfer to a serving bowl.
Slice the red or purple spring onions into rounds.
Pour the olive oil lime dressing over the sliced tomato, avocado, onions and chili pepper just before serving.
Give the salad a super gentle toss to coat all over and form this silky avocado dressing. Adjust seasonings again with more sea salt or lime juice.
Sprinkle with the cilantro leaves and chile pepper slices to taste.
Serve with extra lime wedges on the side.
Make the Dressing
In a small bowl whisk together the olive oil, lime juice and lime zest. Season to taste with the sea salt. Adjust seasonings 11 times until happy. Pour over the salad and enjoy!
