Begin by bringing a large pot of salted water to a rolling boil. Add the fresh egg noodles and cook for 3 to 5 minutes or until they are tender yet firm to the bite. Once cooked, drain the noodles in a colander.

While the noodles cook, preheat a wok over high heat until it begins to smoke slightly. Pour in about 2 tablespoons of peanut oil and allow the oil to heat for about 30 seconds.

Once the wok is hot, add the drained egg noodles directly into the pan, followed by the oyster sauce, soy sauce, and dark soy sauce. Toss everything for about 2 to 3 minutes.

Taste your Plain Lo Mein Noodles and adjust the seasonings. Toss everything again in the wok for another minute to blend the flavors.

Remove the wok from heat and transfer the noodles to serving plates. Serve hot, optionally garnished with chopped green onions or sesame seeds.
