Method
Preparation
Gather all ingredients and chop vegetables into bite-sized pieces.
Mince the garlic and slice the chicken into thin strips.
Cooking
Cook lo mein noodles according to package instructions until al dente; drain and set aside.
Heat a large skillet or wok over medium-high heat and sauté the chicken until golden brown and fully cooked, about 6–8 minutes.
Season lightly with salt and pepper, then remove the chicken from the skillet and set aside.
In the same pan, stir-fry the red bell pepper, yellow bell pepper, carrots, and green onions until tender yet crisp, about 3–4 minutes.
Add the minced garlic in the last 30 seconds.
Return the cooked chicken to the skillet, add the cooked lo mein noodles, soy sauce, sesame oil, and toss everything together until heated through.
Serving
Serve hot with extra soy sauce on the side and garnish with chopped green onions or sesame seeds if desired.
Notes
Cut everything to similar sizes for even cooking. Do not overcrowd the pan; cook in batches if necessary for a nice sear. If noodles stick together, toss with a teaspoon of oil.
