Check the crab for any bits of broken shell and season the crab meat with a little lime juice and salt and pepper.
To make the dressing mix the diced chilli with the lime juice, olive oil and salt and pepper to taste.
In a large bowl break up the chicory leaves and mix with the rocket, mint and coriander. Add about a third of the dressing and toss gently, seasoning with salt and pepper. Divide the salad between four plates and then top with the mango, avocado, crabmeat. Drizzle the remaining dressing over each plate of salad.
