To make the Thai pesto, add the cashew nuts, garlic, chilli, spring onion and fresh coriander (cilantro) to a food processor, and blitz thoroughly. Add the olive oil and coconut milk, and a pinch of salt and pepper, and blitz again until fairly smooth.
Boil the pasta in plenty of water, then drain.
Meanwhile, heat a dash of oil in a large frying pan, and add a couple of handfuls of vegetables. I used chopped red pepper, Tenderstem broccoli, mange tout and baby corn (the exact quantities don't matter at all). Stir fry for 5 minutes until the vegetables have softened slightly.
Add the cooked pasta to the pan, along with the Thai pesto. Mix well, and serve.
