Cook the noodles in boiling water until just tender, drain well.

Heat 1 tablespoon of oil in a wok or very large frying pan and pour in eggs, tilt the pan until you get a thin layer and cook until just set.  Tip egg onto a plate and roll up into a log, slice into thin strips.
Heat remaining oil with sesame oil in the wok and gently cook shallots and carrot until just tender. Add prawns and toss until pink and then add broccoli and 1/4 cup water,soy sauce, fish sauce,  chilli sauce and noodles.  Toss and cook a minute or so before adding chicken, peas, spring onions and half of the sprouts.  Toss until hot and then mix through omelette strips.  Serve topped with remaining mung sprouts and cashew nuts.
