The simple answer is you can pretty much use any type of noodles, with the exception of vermicelli. We wouldn't recommend those for this recipe because of the sauce we use. They will have a tendency to go very slushy ad wet, given the vermicelli noodles are so thin. They are best used in a 'drier' fried noodle recipe, so they maintain their structure. There are many types of noodles available in the shops, ranging from egg noodles (yellow) to rice noodles (white). They also come in different shapes and thicknesses, and as you would expect, recipes will differ according to the type of noodle, as well as the country/region where it is most popular. This recipe for Beef and Vegetable Lo Mein I am sharing is using egg noodles.
