Heat the oven to 200C/180C fan/ gas 6. Mix the squash and chilli in a roasting tin and drizzle with the oil. Add the ginger and season with the white pepper and a pinch of salt. Toss to combine, then roast for 20-25 mins, until the squash is tender.

Meanwhile, prepare the noodles. Heat the oil in a frying pan over a medium heat, then add the spring onion, chilli, garlic and kaffir lime leaves, stirring, until softened and starting to colour, about 5 mins. Reduce the heat to its lowest setting, then add the peanut butter, soy sauce, maple syrup, tamarind paste and 4-6 tbsp water. Stir until the peanut butter melts and you have a loose, creamy, well combined sauce. Remove from the heat and set aside. Cook the noodles following pack instructions, then drain and rinse in cold water.

Add the roasted squash to the pan with the peanut butter sauce and toss to combine, then stir in the noodles. Serve sprinkled with the coriander leaves and lime wedges on the side for squeezing over, if you like.
