In a bowl, toss the chicken pieces with the hoisin sauce, soy sauce, sesame oil, cornstarch, Shaoxing wine, and salt and pepper. Allow the chicken to marinate for at least 30 minutes preferably a few hours.
1 pound boneless skinless chicken breasts or thighs, 1 tablespoon hoisin sauce, 2 tablespoons soy sauce, 2 teaspoons sesame oil, 1 tablespoons cornstarch, 1 tablespoon Shaoxing wine or dry sherry, Salt and pepper to taste
Heat the vegetable oil in a large skillet or wok over medium-high heat. Add the chicken pieces and cook until they are browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set it aside.
2 tablespoon vegetable oil
In a bowl, whisk together the soy sauce, chicken broth, brown sugar, sesame oil, and crushed red pepper flakes. Set aside.
2 tablespoons low-sodium soy sauce, 1/4 cup chicken broth, 1 tablespoon brown sugar, 1 teaspoon sesame oil, 1/4 teaspoon crushed red pepper flakes, 1 tablespoon cornstarch
In the same skillet, add 2 tablespoons of vegetable oil. Add the minced garlic and grated ginger. Sauté for about 30 seconds until fragrant.
2 tablespoon vegetable oil, 2 cloves garlic, 1 teaspoon grated ginger
Add the green beans and sliced white onion to the skillet. Stir-fry for about 3-4 minutes until they start to soften but are still crisp-tender. Pour the sauce over the vegetables then bring to a simmer. Allow it to cook for 2-3 minutes or until it has slightly thickened.
1 pound fresh green beans, 1 cup white onion
Return the cooked chicken to the skillet and stir to coat it with the sauce. Cook for an additional 2-3 minutes, or until the chicken is heated through and well-coated with the sauce.
Serve your string bean chicken over steamed rice and garnish with chopped green onions.
