Begin by heating a large skillet or wok over medium-high heat for about 2 minutes until it shimmers.

Add the ground beef to the hot skillet, breaking it up with a spatula as it cooks for 5–7 minutes until browned.

In a small bowl, whisk together soy sauce, brown sugar, minced garlic, and grated ginger until smooth.

Pour the prepared sauce into the skillet with the cooked beef. Stir together and let simmer for 3–4 minutes.

Meanwhile, bring a pot of salted water to a boil and cook the noodles according to package instructions until al dente.

Toss the cooked noodles into the skillet with the beef and sauce mixture, stirring gently until coated.

Remove from heat and serve warm, garnished with chopped green onions.
