Prepare the Sauce:
In a small bowl, whisk together soy sauce, oyster sauce, honey, cornstarch, chicken broth, sesame oil, and rice vinegar (if using). Set aside.
Cook the Chicken:
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the chicken strips and stir-fry for 5–6 minutes, or until cooked through. Remove the chicken from the skillet and set aside.
Stir Fry the Vegetables:
Add the remaining oil to the skillet. Add broccoli, bell pepper, carrot, and snap peas. Stir-fry for 3–4 minutes until the vegetables are crisp-tender. Add garlic and ginger, stir-frying for an additional minute.
Combine and Cook:
Return the chicken to the skillet. Pour in the prepared sauce and stir well to coat everything evenly. Cook for 2–3 minutes until the sauce thickens and coats the chicken and vegetables.
Serve:
Remove from heat and serve immediately over steamed rice or noodles. Garnish with sesame seeds or chopped green onions, if desired.
