Cook the pasta in plenty of boiling salted water for 10-12 minutes until al dente. Meanwhile drain the pineapple and cut into pieces. Clean and wash spring onions and cut into rings. Peel and halve the onions and cut into fine strips.
Cut the turkey breast into large cubes. Mix vinegar, salt, pepper and sugar. Whip oil into it. Drain noodles, rinse with cold water and drain. Mix with the vinaigrette. Stir in pineapple, spring onions, onion rings and diced turkey breast.
Leave to stand for about 30 minutes and season again. Arrange on salad leaves. Garnish with crushed pink berries and parsley.
