Fill a large pot with water and bring it to a boil. Add the lo mein noodles and cook them according to the package instructions until they reach an al dente texture. Once cooked, drain the noodles in a colander and set them aside for later use.
In a mixing bowl, combine the thinly sliced chicken breast with soy sauce and oyster sauce (if using). Ensure the chicken is well coated in the marinade, then let it rest for about 10 minutes to absorb the flavors.
Place a large skillet or wok over medium-high heat. Add the vegetable oil and wait until it’s hot. Introduce the minced garlic and grated ginger, stirring them quickly for about 30 seconds until they become fragrant but not burnt.
Add the marinated chicken to the skillet. Sauté for 4-5 minutes, stirring frequently, until the chicken is no longer pink in the center and has achieved a light golden-brown color. Once cooked, remove the chicken from the skillet and set it aside.
Using the same skillet, add the sliced bell pepper, julienned carrot, and snap peas. Stir-fry these vegetables for about 3-4 minutes until they are tender-crisp and vibrant in color.
Return the cooked lo mein noodles and sautéed chicken to the skillet. Drizzle the mixture with sesame oil and toss everything together until the ingredients are mixed well. Season with salt and pepper to your liking. Cook for an additional 1-2 minutes to heat everything through.
Gently fold in the sliced green onions and ensure all ingredients are well combined and heated adequately.
Notes
Serve in large bowls topped with sesame seeds and extra green onions.
