Feel free to choose your favorite noodles traditionally egg noodles are used but any thicker noodle works great! This recipe is a great way to use up any veggies going bad in your fridge. So any combination of veggies will work. You can even add protein like tofu or chicken. If you can't find vegetarian oyster sauce then hosin sauce will work well as a vegetarian substitute. The chili oil is optional as well, depending on your spice tolerance you can adjust the amount or completely omit it.
