01 - In a medium bowl, combine soy sauce, brown sugar, and water. Stir until the sugar dissolves completely. Set aside.
02 - Heat vegetable oil in a large skillet or wok over medium-high heat until shimmering.
03 - Add chicken pieces to the hot pan. Cook for 4 to 5 minutes, turning frequently to brown all sides evenly.
04 - Add minced garlic and grated ginger to the pan. Sauté for 1 minute until fragrant, stirring constantly to prevent burning.
05 - Pour the prepared sauce over the chicken. Stir well to coat all pieces evenly.
06 - Bring to a simmer and cook for 6 to 8 minutes, or until the sauce thickens and coats the chicken. Ensure chicken is cooked through to an internal temperature of 165°F.
07 - Remove from heat. Garnish with sliced green onions if desired. Serve immediately with steamed rice or noodles.
