First marinade the turkey. Whisk the soy sauce, lime juice, sugar, chilli powder and five-spice together. Put the turkey in a dish, pour over the marinade and toss. Cover with cling film and leave to stand.
For the peanut sauce, heat the oil in a frying pan and add the shallots. Cook on a medium heat until they are translucent and have taken on some colour, then add the garlic, ginger and chillies.
Continue to cook, stirring regularly, for another 2–3 minutes, then add the remaining sauce ingredients. Stir, then simmer until the sauce has reduced down. Leave to cool.
To assemble the salad, arrange all the vegetables over a large serving platter. Use a tablespoon or so of the sauce to coat the turkey, then place this on top. Drizzle over a little more of the sauce, then garnish with the chillies, herbs and peanuts.
