Cook the egg noodles in salted boiling water until soft. Drain and run under cold water and let them dry out in a colander.
Let the prawns and broccoli defrost for at least 30 minutes at room temperature.
In a wok or large pan, heat the vegetable oil, then add the garlic, spring onions, ginger, chilli, prawns and broccoli. Stir fry for 2 minutes while the prawns become less translucent, and then add the noodles.
Make sure to thoroughly mix all the noodles with the other ingredients, then add the soy sauce and sesame oil, and continue to stir fry for another minute
