Brush the chicken or duck with a little olive oil and season with salt and pepper. Grill or saute until tender. Slice or shred into 1/2 inch strips.
Mix the lime juice, fish sauce, soy and groundnut oil. Add a shake or two of sesame oil. Stir in the sugar, garlic and chopped mint. Season with black pepper.
Slice the cucumber and carrot finely, shaving with a vegetable peeler. Toss with the dressing in a large bowl, together with the coriander, chilli, onion and beans sprouts.
Toss in the chicken ( or duck, prawns or squid). Serve immediately.
