Whisk the sauce. In a small bowl, mix soy sauce, rice vinegar, honey, sesame oil, sriracha, and broth. If you prefer a glossy, thicker sauce, whisk in cornstarch until smooth.
Set aside.
Prep the veggies. Slice and chop all vegetables so they’re ready to go. Stir fry moves fast, so having everything prepped first helps keep the vegetables crisp-tender.
Brown the turkey. Heat 1 tablespoon oil in a large skillet or wok over medium-high heat. Add ground turkey and the white parts of the green onion.
Season lightly with salt and pepper. Cook, breaking it up with a spatula, until no longer pink and lightly browned, about 5–7 minutes. Transfer to a plate.
Sauté aromatics. Add remaining oil to the pan.
Toss in onion, garlic, and ginger. Cook for 30–60 seconds until fragrant, stirring often to avoid burning.
Cook the vegetables. Add broccoli and carrots. Stir fry for 2–3 minutes.
Add bell pepper and snap peas. Cook another 2–3 minutes until vegetables are bright and crisp-tender.
Combine and sauce. Return the turkey to the pan. Give the sauce a quick stir, then pour it over the mixture.
Stir continuously for 1–2 minutes until the sauce thickens slightly and coats everything.
Finish and taste. Sprinkle in the green onion tops and sesame seeds. Taste and adjust: add a splash more soy sauce for salt, a squeeze of lime for brightness, or extra chili sauce for heat.
Serve. Spoon over rice, quinoa, or cauliflower rice. Garnish with fresh herbs if you like.
Serve hot.
