Finely chop the scallions, separating the green and white parts, and set them aside.

In a small bowl, combine the light soy sauce, dark soy sauce, and sugar. Stir until the sugar dissolves.

In a medium-sized pan, heat about 2-3 tablespoons of cooking oil over medium heat until shimmering.

Add the white parts of the chopped scallions to the hot oil. Sauté for 1-2 minutes until fragrant and slightly crispy.

Carefully pour the hot oil and sautéed scallions over the pre-mixed sauce in the bowl. Stir to combine.

Bring a pot of water to a rolling boil, then add the wheat noodles. Cook according to package instructions, usually 4-6 minutes.

Drain the noodles and combine them in a bowl with the scallion oil sauce. Toss well to coat.

Serve the noodles and garnish with the green parts of the fried scallions.
