Add 225 g dried rice vermicelli noodles to a large heatproof bowl. Cover with plenty of hot water — it's crucial the water is neither boiling nor cold — and soak for 10 minutes. The noodles should loosen up yet remain slightly firm.
Drain the rice noodles in a large colander and set aside. As a precaution, you can toss the noodles with oil to prevent them from sticking together. I usually find this unnecessary.
Cook the Stir Fry
Heat a large wok over high heat until smoking. Once hot, add 1 tablespoon oill and swirl around.
Add 40 g onion and 1 tablespoon fresh ginger to the pan. Stir-fry for a few seconds, tossing/stirring constantly.
Next, add the vegetables with longer cooking time to the pan. For this recipe, 1 carrot, 1 pak choy, and 60 g napa cabbage. Also, add your chosen protein — 2 vegan hot dogs. Stir-fry for a few minutes on high heat, until the sausages are slightly charred, and the vegetables are tender but still crisp.
Throw in 100 g beansprouts and 5 spring onions. Stir fry for 30 seconds.
Add 2 tablespoons light soy sauce**and 1 teaspoon dark soy sauce** plus 1 teaspoon vegan oyster sauce to the pan. Toss to mix with the vegetables.
Add the soaked and drained rice noodles to the pan. Use a combination of tossing and stirring movements to mix everything well. Turn off the heat.
Finish the dish with a drizzle of 1 teaspoon sesame oil. Garnish with spring onion greens, if desired.
Notes
You can skip this step if you're using pre-soaked, fresh rice noodles.** To make veggie mei fun gluten free, substitute soy sauce for tamari. You may also need to check the ingredients of the vegan oyster sauce.
