Combine the oil, garlic, chilli, lemon rind and salt and pepper to taste in a non-metallic bowl, add the prawns and stir well. Cover and leave to marinate in the refrigerator for 1 hour.
Cook the pasta in a large saucepan of salted boiling water for about 3 minutes until al dente, then drain.
Meanwhile, heat a wok or large frying pan until hot and add a drizzle of oil. Tip in the prawn mixture and the spring onions and stir-fry over a high heat for 2–3 minutes until the prawns are lightly browned. Add the lemon juice and basil and stir well.
Serve the prawns immediately with the cooked pasta.
