Smoked mackerel salad

Method

1. Gently break the mackerel into bite-size chunks and put in a serving bowl. Slice the avocado into chunks, then squeeze over a little lemon juice to prevent it browning.
2. Add the avocado, tomatoes, lentils, salad leaves and chives to the mackerel. Whisk the lemon juice with sea salt, black pepper and a pinch of caster sugar, then whisk in the olive oil. Pour over the salad, toss gently, then serve.
