Wait for the noodles to finish soaking, then drain in a colander.
Heat wok to medium high heat.
Add about a tablespoon of oil to the wok.
1 tablespoon grapeseed oil
Add onion and garlic to the wok. Sautee until fragrant and lightly brown, 3-6 minutes.
Deglaze the wok with the sauce. Taste the sauce and add ingredients if necessary to find a balance between sweet, spicy, salty, and sour. See notes on how to get these flavors.
Add the crispy mushrooms to the wok.
Add the noodles and stir fry until the noodles have absorbed the sauce. About 3-6 minutes. Taste test a noodle to ensure fully cooked. If the noodles look dry, add water a tablespoon at a time.
When the noodles are cooked completely, turn off the heat and fold in the bean sprouts and green onions. Folding the noodles over the bean sprouts and green onions allows the vegetables to cook slightly. Let sit for a couple of minutes.
Give it one last stir to incorporate all the ingredients and serve garnished with peanuts and lime!
