Boil water in a pot and cook the instant ramen noodles according to package instructions until al dente, usually around 4-5 minutes.

While the noodles are cooking, in a separate pan, heat the sesame oil over medium heat.

Add the shredded chicken and chopped vegetables to the pan and stir-fry for 3-4 minutes until heated through.

In a bowl, mix the Buldak sauce, soy sauce, and sugar together.

Once the noodles are cooked, drain them and add to the pan with chicken and vegetables.

Pour the sauce mixture over the noodles and toss everything together until well combined and heated through.

Serve the Buldak noodles hot, garnished with chopped green onions, sesame seeds, and a halved boiled egg if desired.
