Place a pot of water, ½ tbsp oil, and ½ tsp salt on the stovetop on high. Add noodles to cook until al dente per package instructions. (Mine required placing noodles in boiling water, turning off stove, covering for 5-7 minutes)
Meanwhile, chop bell peppers and carrots into julienne (thin strips). Chop cabbage finely. Cut spring onions, separating whites and greens. Use garlic crusher to crush garlic and shred ginger.
Once noodles are cooked per package instructions to al dente, drain noodles in a colander/strainer. Then, rinse with cold water. Set aside.
Heat remaining 2 tbsp of oil in a wok on medium-high. Add ginger and garlic to pan. Mix and let cook 1 minute.
Add spring onion whites then greens (save some greens for adding later). Mix and let cook 1-2 minutes.
Add chopped bell peppers, carrots, and cabbage. Add salt, sugar, and white pepper. Toss to mix.
Add noodles, soy sauce and red chili sauce. Toss to mix. Let cook 3-5 minutes on medium. Mix in between so noodles don't stick too much.
Add vinegar and toss to mix. Turn off gas. Sprinkle green onions and toasted sesame seeds to finish the dish.
