Place the prunes in 2 tbsp of orange juice and simmer for 2 minutes, until the prunes are slightly soft. Remove from the juice and cool – reserve the juice. Take the orange peel and segment them and set aside.
To make the dressing, mix all of the ingredients together and season with sea salt and black pepper. To assemble the salad, divide the rocket and watercress leaves between 4 plates, layer up the leaves, with the turkey, orange segments, prunes and pecan nuts.
Dress the salads and garnish with the chives if you wish.
