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 4–5 minutes, turning occasionally to brown all sides evenly.
04 - Add minced garlic and grated ginger. 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. Bring to a simmer and cook for 6–8 minutes, or until sauce thickens and chicken is cooked through.
06 - Remove from heat. Garnish with sliced green onions if desired. Serve immediately with steamed rice or noodles.
