Let the pasta soften in a bowl of boiling water (for about 3-4 minutes).
Let the oil get hot in a saucepan or large wok. Add the diced chicken and fry for 5 minutes until lightly browned. Add the white pieces of spring onions, garlic and ginger, stir well and fry for 2 minutes. Add the broth, coconut milk, curry paste, peanut butter and soy sauce, season with salt and pepper and bring to the boil. Stir and simmer for 8 minutes.
Stir every now and then. Add paprika, peas and the green pieces of spring onions and simmer for another 2 minutes. Add the drained noodles to the soup and heat. Serve the soup in warmed bowls. If you don`t like it that spicy, just use green curry paste.
