In a small saucepan, combine soy sauce, brown sugar, ¾ cup of water, honey, garlic, ginger, and orange zest. Stir and bring to a simmer over medium heat.
In a separate bowl, whisk cornstarch with the remaining ¼ cup of water until smooth. Slowly pour it into the sauce, stirring constantly until the sauce thickens. Remove from heat and set aside.
Heat sesame oil in a large skillet or wok over medium-high heat. Add ground turkey and cook until browned, breaking it apart as it cooks. Season with salt and pepper.
Add diced onion, shredded carrots, and broccoli florets. Stir-fry for 4-5 minutes until the vegetables are tender-crisp.
Pour the teriyaki sauce over the turkey and vegetables, stirring to coat evenly. Let everything cook together for another 2 minutes.
Serve hot, garnished with sesame seeds or green onions if desired. Enjoy with rice, quinoa, or noodles!
