In a saucepan, gently heat the vinegar, sugar and salt, just until the sugar dissolves, for up to a minute. Remove from the heat and add the garlic, chilli and sesame oil. Set aside to cool, then add the lime zest and juice.
Heat the sunflower oil in a large pan and shallow-fry the aubergine in three or four batches. Once golden-brown, transfer to a colander, sprinkle liberally with salt and leave to drain.
Cook the noodles in plenty of boiling, salted water, stirring occasionally, for five to eight minutes - the noodles should retain a bite - then drain and rinse under cold water. Shake off the excess water and place on kitchen towel to dry.
In a mixing bowl, toss the noodles with the dressing, aubergine, onion, mango and half the herbs. You can leave it aside for an hour or two. When ready to serve, add the rest of the herbs, mix and pile on a plate or in a bowl.
