I bring a pot of water to a boil, then cook the lo mein noodles until just tender—usually around 4 to 5 minutes. I drain and rinse them under cold water to stop the cooking and keep them from sticking together. Set them aside while everything else comes together.
I toss the thinly sliced chicken breast with cornstarch and a teaspoon of soy sauce. This helps the meat stay tender while adding flavor. In a hot skillet with vegetable oil, I sear the chicken in a single layer until it’s golden and cooked through—about 5–6 minutes. Then, I take it out and keep it warm.
Next, I add a bit more oil to the skillet, then sauté garlic for a few seconds until fragrant. I follow that with carrots, cabbage, and bell peppers. Stirring often, I cook them for about 3–4 minutes until just tender but still crisp. The goal is to keep the veggies colorful and slightly crunchy.
While the veggies cook, I mix the sauce: soy sauce, hoisin, oyster sauce, sesame oil, sugar, and a splash of water. Once the vegetables are ready, I return the chicken to the pan and pour in the sauce. Everything gets a good stir so it’s well coated.
Now it’s time to toss in the cooked noodles. I gently stir everything together, making sure the noodles soak up all the sauce. In about 2 minutes, it’s done! I throw in the green onions at the end for a fresh finish.
