Prep the sauce: In a small bowl, whisk together soy sauce, rice vinegar, sriracha, honey, and the cornstarch slurry if using. Set aside.
Heat the pan: Place a large skillet or wok over medium-high heat.
Add oil. When hot, add onion and cook 2–3 minutes until slightly softened.
Brown the turkey: Add ground turkey. Break it up with a spatula and cook 5–7 minutes until no longer pink.
Season with a pinch of salt and pepper.
Add aromatics: Stir in garlic and ginger. Cook 30–60 seconds until fragrant. Avoid burning.
Add the veggies: Toss in broccoli, bell pepper, carrots, and snap peas.
Stir-fry 4–6 minutes, until tender-crisp. If the pan gets dry, add a splash of water.
Sauce it up: Pour the sauce over the turkey and vegetables. Stir well to coat.
Let it bubble 1–2 minutes until slightly thickened. Remove from heat and finish with sesame oil.
Taste and adjust: Add more soy for salt, vinegar for brightness, or sriracha for heat. Garnish with green onions and sesame seeds.
