Prep the chicken. In a bowl, toss sliced chicken with 2 tablespoons soy sauce and 1 tablespoon cornstarch. Set aside while you prep the vegetables. This quick marinade keeps the chicken juicy.
Make the sauce. In a small bowl, whisk soy sauce, oyster sauce, rice vinegar, honey, broth, cornstarch, and sesame oil.
Add chili if you like heat. Keep it nearby—you’ll need it fast.
Preheat the pan. Heat a large skillet or wok over medium-high until hot. Add 1 tablespoon oil.
Cook the chicken. Spread the chicken in a single layer.
Let it sear for 1–2 minutes before stirring. Cook 4–5 minutes total until just cooked through. Transfer to a plate.
Sauté the aromatics. Add another tablespoon of oil.
Cook ginger, garlic, and the white parts of green onions for 30 seconds, stirring so they don’t burn.
Stir fry the veggies. Add broccoli, bell pepper, and carrot. Stir fry 3–4 minutes until crisp-tender. If needed, splash in a tablespoon of water to help steam the broccoli.
Combine and sauce. Return chicken and any juices to the pan.
Stir the sauce (cornstarch settles), then pour it in. Toss for 1–2 minutes until glossy and slightly thickened.
Finish and serve. Turn off the heat. Add green onion tops and a sprinkle of sesame seeds.
Taste and adjust with a little soy, vinegar, or honey. Serve over rice or noodles.
