Heat oil in a large skillet over medium-high heat. Add ground chicken and cook, breaking it apart with a spatula, until fully browned and cooked through (about 5–6 minutes). Drain excess liquid if needed.

In a small bowl, whisk together orange juice, orange zest, soy sauce, honey, rice vinegar, and cornstarch until smooth.

Push the chicken to one side of the pan. Add the minced garlic and grated ginger to the open space and sauté for about 30 seconds until fragrant.

Pour the orange sauce over the chicken mixture. Stir everything together and let it simmer for 3–5 minutes, until the sauce thickens and coats the chicken evenly.

Remove from heat and garnish with green onions, sesame seeds, and/or red pepper flakes if desired. Serve hot over rice, noodles, or in lettuce wraps.
