Cook the noodles al dente and rinse in cold water. Drain. Make a dressing from whole milk yoghurt, 0.5 bunch of rocket, basil, mayonnaise, salt, pepper, sugar and lemon juice with a hand blender.
Halve or third the remaining rocket, depending on your taste. Mix with corn, spring onions, cherry tomatoes and pasta. Mix with the yogurt dressing just before serving and sprinkle with fresh pepper again.
