Heat the vegetable oil in a wok until hot, then cook the broccoli, tossing, for 4-5 minutes or until really charred. Pour in 50ml of water and cook until the water has evaporated. Turn the heat down, add the spring onions, garlic and chilli, and cook for 2 minutes. Make a well in the middle of the vegetables and drop in the beaten egg. Leave it to set, then roughly chop it up with a spoon in the pan and stir it through the vegetables. Tip in the sauce and noodles, and toss everything together for several minutes.
