Fill a large pot with water and bring it up to a rolling boil. Cook the noodles as directed on the package until they're just tender. Drain and set aside.
In a small bowl, whisk together soy sauce, rice vinegar, chili paste, sugar, sesame oil, and red pepper flakes until blended. Set this sauce mix aside.
Warm the vegetable oil in a wide skillet over medium heat. Toss in the minced garlic and ginger, cooking until their aroma fills the kitchen, about 1-2 minutes.
Pour the prepared sauce into the skillet and stir well so it melds with the garlic and ginger.
Add the water to the pan and let the sauce bubble gently for 2-3 minutes, allowing it to thicken slightly.
Introduce the cooked noodles to the skillet and toss everything thoroughly, making sure the noodles are coated in the sauce.
Once the noodles are heated through, take the skillet off the heat.
Serve the Chili Garlic Noodles on a plate,
and finish by sprinkling chopped green onions and sesame seeds over the top. Dig in and enjoy!
