When oven is a desired cooking temperature place potatoes on a shelf in the middle and allow them to cook for 45m – 1 hour until crispy on the outside and soft on the inside.
Meanwhile, whilst the potatoes are cooking make the Coronation Turkey.
Grill the turkey breasts, allow them to cool and then dice them.
Cook the sweetcorn and allow to cool
Place the turkey, sweetcorn, onion, mayonnaise, curry powder, mango chutney and coriander into a bowl. Season with the black pepper and mix together. Place in the refrigerator until the potatoes are cooked.
Cut the potatoes in half, fill with the Coronation Turkey and serve with steamed vegetables or a salad.
