Start by cooking the egg noodles in boiling water based on the package instructions.
Drain them well and set aside.
Heat the peanut oil in a large skillet or wok over medium-high heat.
Add the sliced chicken and cook until golden brown.
Transfer the chicken to a separate plate.
In the same pan, add garlic, ginger, carrots, shiitake mushrooms, and bean sprouts.
Stir-fry them for about 3-5 minutes until they’re crisp-tender.
Combine the chicken broth, soy sauce, and sugar in a small bowl.
Pour it into the skillet, stirring to coat the vegetables well.
Return the chicken to the pan along with the cooked noodles.
Mix everything thoroughly until heated through.
Garnish with chopped green onions just before serving.
