**Cook the noodles** Bring a large pot of salted water to a boil. Add noodles and cook according to package instructions until al dente. Drain, rinse under cold water to stop cooking, and set aside.
**Heat the wok** In a wok or large skillet over medium-high heat, warm the vegetable oil.
**Sauté garlic and chilies** Add the minced garlic and chopped chilies. Stir-fry for about 30 seconds to 1 minute, being careful not to let them burn.
**Add vegetables** Toss in the sliced vegetables. Stir-fry for 2–3 minutes, keeping them slightly crunchy.
**Combine noodles and sauce** Add the cooked noodles to the wok. Drizzle in soy sauce, chili sauce, and vinegar or lime juice (if using). Toss everything together for 1–2 minutes, ensuring the noodles are well coated and heated through. Season with salt and black pepper.
**Serve** Transfer the chilli garlic noodles to a serving plate. Garnish with sliced green onions or sesame seeds if desired.
