Peel the prawns, leaving the tail intact. Use the tip of a knife to remove the digestive tract.
Peel the mango, remove the stone and cut the fruit into strips. Peel the red onion and cut into strips a similar size to the mango. Wash and pick the coriander leaves.
Cut each sheet of pastry into 8 equal sized triangles. On each triangle place one gamba, a wedge of mango and red onion, some coriander leaves, salt and pepper. Seal the triangles and prick with a fork/toothpick.
