500g cucumber (about half an English cucumber)
30ml lemon juice
2 salad onions, finely sliced
Peel the cucumber in alternating strips in its length.
Take out the seeds with a teaspoon, cut into bite-sized pieces and put it in a colander set in your sink.
Sprinkle 5ml salt over, toss together and leave to drain for about 20 minutes.
Slice the avocado in half, remove the pip and scoop out the flesh.
Cut in to 1,5cm cubes.
Add the avocado to a mixing bowl, sprinkle over the lemon juice and season with salt and black pepper. Stir to combine.
Shake the cucumber pieces in the colander to get rid of any moisture.
Add to the avocado.
Add the sliced salad onions and mix again.
Now stir the salad vigorously until the avocado breaks down a bit.
Taste the salad and adjust the seasoning with salt, pepper and lemon juice.
Scatter over some chilli flakes and serve.
