Heat the sesame oil in a pan, then add the red onion, garlic and chilli and fry for a couple of minutes.
Add the broccoli and pepper and fry for a further 5 minutes until softened.
Meanwhile, place some rice noodles on the boil (follow the packet instructions) and prepare the pad Thai sauce by adding all the ingredients into a small bowl and mixing until smooth.
Add a large handful of beansprouts, crushed peanuts, lime juice and the sauce to the pan and cook together for a couple of minutes.
Finally, add the noodles to the pan and stir in to soak up all the sauce.
Serve with extra beansprouts, chilli, lime and crushed peanuts.
