In a large mixing bowl, combine the thinly sliced chicken breast with the cornstarch and 1 tablespoon of soy sauce. Mix thoroughly and let it marinate for 15 minutes.
In a large pan or wok, heat 1 tablespoon of sesame oil over medium-high heat. Add the marinated chicken and stir-fry for 4-5 minutes until fully cooked and golden brown. Transfer to a plate and set aside.
In the same pan, pour in the remaining tablespoon of sesame oil. Add minced garlic and ginger, sautéing for about 30 seconds until fragrant.
Add broccoli florets, sliced bell pepper, and julienned carrot to the pan. Stir-fry for 3-4 minutes until tender-crisp.
Return the cooked chicken to the pan. In a small bowl, whisk together the remaining soy sauce, honey, and chicken broth. Pour over the chicken and vegetables, stirring to coat. Cook for an additional 1-2 minutes to thicken the sauce.
Remove the pan from heat once everything is mixed and heated through.
Serve the stir-fry on plates or in bowls, garnished with sesame seeds and green onion slices.
Notes
Serve over steamed rice or quinoa for a complete meal. Lime wedges add a zesty touch.
