Creating delicious Chinese Scallion Chicken is straightforward if you follow these steps:

1. Prepare the Chicken: Slice the boneless, skinless chicken breasts into thin strips.
2. Marinate the Chicken: In a bowl, combine the sliced chicken, soy sauce, sesame oil, minced ginger, and minced garlic. Mix well and let it marinate for about 10 minutes.
3. Add Cornstarch: After marinating, sprinkle cornstarch over the chicken and toss to coat evenly. This will help create a crispy texture.
4. Heat Oil: In a large skillet or wok, heat vegetable oil over medium-high heat.
5. Cook Chicken: Add the marinated chicken to the skillet, ensuring the pieces are in a single layer. Cook for about 5-7 minutes, stirring occasionally, until the chicken is cooked through and no longer pink.
6. Add Scallions: Once the chicken is nearly done, add chopped scallions to the skillet. Stir-fry for an additional 2-3 minutes, allowing the scallions to wilt slightly.
7. Season: If desired, season with salt, pepper, and red pepper flakes for extra heat.
8. Serve: Remove the skillet from heat and transfer to a serving platter.
