1. Preheat oven to 190Â°C/375Â°F/Gas Mark 5, 10 minutes before cooking. Wipe the turkey breast fillets and make 3 diagonal slashes across each breast. Gently heat the ingredients for the glaze and spoon over the turkey fillets.
2. Cook in the pre-heated oven for 25-28 minutes or until thoroughly cooked. Baste the turkey occasionally with the glaze.
3. Meanwhile, chop the potatoes and parsnips into small chunks then cook in lightly salted boiling water for 15-20 minutes or until tender when pierced with a fork. Drain thoroughly then mash with seasoning to taste and the milk or yoghurt. Beat well with a fork until creamy then stir in the chopped parsley.
4. Arrange the mash onto 4 individual warmed plates and top with the glazed turkey fillets. Garnish with fresh parsley sprigs and orange slices. Serve with salad or freshly cooked vegetables.
