The original of this comes from the back of a packet of Chang’s original fried noodles. I make the same dressing, but like a few extra salad ingredients. Original dressing contains olive oil-I find it too heavy and prefer to use canola. Make the dressing ahead of time to allow it to cool. Only add the noodles THE MOMENT you are about to eat or pass them around seperately if there is a chance of left-overs.
