Bring a large pot of salted water to a rolling boil. Carefully add the lo mein noodles and cook according to package instructions until al dente. Drain the noodles in a colander and set them aside, tossing with a small drizzle of oil to prevent sticking.
In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat. Once hot, add the sliced chicken, seasoning it with salt and pepper. Sauté for 5-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through. Remove the chicken from the skillet and set it aside on a plate.
In the same skillet, add the remaining tablespoon of vegetable oil. Introduce the minced garlic and grated ginger, stirring for about 30 seconds until fragrant. Then, add the broccoli florets, sliced red bell pepper, and snap peas. Stir-fry the mixture for approximately 4-5 minutes, or until the vegetables are tender yet still vibrant and crisp.
Reintroduce the cooked chicken back into the skillet with the vegetables. Add the cooked lo mein noodles, soy sauce, oyster sauce, and sesame oil. Gently toss all the ingredients together with tongs or a spatula, cooking for an additional 2-3 minutes until everything is heated through and evenly coated in the sauce.
Once everything is well combined and piping hot, gently fold in the chopped green onions. Remove the skillet from heat. Serve your lo mein hot, garnished with a sprinkle of sesame seeds for an added crunch and visual appeal.
Notes
For a delightful touch, consider serving the lo mein in individual bowls or take-out containers, garnished with a few additional green onions and a sprinkle of sesame seeds for that authentic feel.
