Peel the papaya and quarter to make it more manageable. Remove seeds, then grate.
In a bowl, combine the papaya, tomato, chili and prawns. Add the juice, fish sauce, garlic and half of the coriander and gently toss to ensure it is all well mixed and coated.
Arrange the lettuce on plates and spoon the salad on top.
Finish with the remaining coriander, basil and beans (optional)
