Step 1: Prepare the Chicken

• Season the chicken pieces with salt, pepper, and cornstarch. This helps create a slightly crispy texture when cooked.

Step 2: Cook the Chicken

• Heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat. Add the chicken and cook for 4-5 minutes, stirring occasionally, until the chicken is browned and cooked through. Remove the chicken from the skillet and set aside.

Step 3: Prepare the Sauce

• In the same skillet, add the white parts of the scallions, garlic, and ginger. Sauté for 1-2 minutes until fragrant.
• Stir in the soy sauce, oyster sauce, rice vinegar, chicken broth, and sugar. Bring to a simmer and cook for another 2-3 minutes, allowing the sauce to thicken slightly.

Step 4: Combine Chicken and Sauce

• Return the cooked chicken to the skillet and toss it in the sauce. Add the green parts of the scallions and stir everything together. Cook for another 1-2 minutes until the chicken is fully coated and heated through.

Step 5: Serve

• Remove from heat and drizzle with sesame oil (if using) before serving.
