Make the sauce: In a small bowl, whisk soy sauce, oyster sauce, rice vinegar, honey, sriracha, water, and cornstarch until smooth. Set aside.
Prep the veggies: Slice and chop everything before you start cooking.
Stir fry moves fast, so have it all ready.
Heat the pan: Set a large skillet or wok over medium-high heat. Add neutral oil and swirl to coat.
Brown the chicken: Add ground chicken. Break it up with a spatula and cook 4–6 minutes until lightly browned and cooked through.
Season with a pinch of salt and pepper. Transfer to a plate if the pan feels crowded.
Sauté aromatics: In the same pan, add onion, garlic, and ginger. Cook 1–2 minutes until fragrant.
Avoid burning the garlic.
Cook the vegetables: Add bell pepper, broccoli, and snap peas. 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.
Whisk the sauce again, then pour it in. Stir constantly 1–2 minutes until the sauce thickens and coats everything.
Finish: Turn off heat. Stir in sesame oil and the white parts of the green onions.
Taste and adjust seasoning—more soy for salt, more honey for sweetness, or a squeeze of lime for brightness.
Serve: Top with green onion tops and sesame seeds. Spoon over rice or noodles, or tuck into lettuce cups.
