Fried noodles are optional. They are an authentic ingredient though. If you can get fresh Chinese egg noodles consider it. Heat about one inch of oil in a wok. As it heats test the oil with a small piece of fresh noodle. When it bubbles the oil is hot enough. Add a nest of noodles to the oil. They will crisp up quickly. Flip them using tongs. The whole process takes less than a minute. Set aside on paper towel to drain. You can make these in advance.
