Prepare the ingredients by dicing the chicken and chopping the vegetables.

Cook the lo mein noodles according to package instructions; drain and set aside.

In a skillet or wok, heat oil over medium-high heat. Sauté chicken until golden brown and cooked through (about 5 minutes).

Add minced garlic and mixed vegetables; cook for another 3-4 minutes until veggies are tender-crisp.

In a bowl, whisk together soy sauce, sesame oil, cornstarch, and a splash of water. Pour over chicken and vegetables.

Toss in cooked noodles until well coated with sauce; heat through for an additional minute.
