Cook the Noodles: Prepare the noodles according to package instructions. Drain and set aside.
Cook the Beef: Heat vegetable oil in a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it apart with a spoon. Drain excess fat if necessary.
Add Aromatics: Stir in garlic and ginger, cooking for 1–2 minutes until fragrant.
Prepare the Sauce: In a small bowl, mix soy sauce, brown sugar, hoisin sauce, and water. Pour over the cooked beef, stirring to combine. Let it simmer for 2–3 minutes until slightly thickened.
Combine with Noodles: Add the cooked noodles to the skillet. Toss everything together to coat the noodles evenly with the sauce.
