Place ¾ mango, the celery, spring onions, lime zest and juice into a food processor. Whizz together while pouring in the oil.
Finely chop half the coriander and add to the blender along with the chicken, cucumber, tomatoes and beansprouts.
Cut the remaining mango into 3cm cubes and mix in. Place the salad on a plate and garnish with sprigs of coriander and toasted coconut. Serve with the rocket.
