Cook the noodles al dente and drain. Cut the spring onions into rings and the sun-dried tomatoes into strips. Briefly dry roast the pine nuts in a pan.
Mix the pasta, spring onions, tomatoes, olive oil and pine nuts together in a bowl. Season with garlic, oregano and a little balsamic vinegar and season the salad with salt, pepper and chili powder.
The salad tastes best when it can steep for about 2 hours.
