Make the Teriyaki Sauce:
In a small saucepan over medium heat, combine 3/4 cup water, soy sauce, minced garlic, grated ginger, honey, and brown sugar. Stir to combine and bring the mixture to a low boil.
In a separate small bowl, whisk together 1/4 cup water and corn starch until the corn starch is completely dissolved, creating a slurry.
Slowly stir the slurry into the boiling sauce mixture and allow it to thicken. Once thickened, remove the saucepan from the heat and stir in the orange zest. Set the sauce aside until ready to add to the stir fry.
Prepare the Stir Fry:
Heat the sesame oil in a wok or large skillet over medium-high heat. Add the diced onion and cook for several minutes until softened.
Add the ground turkey to the skillet and cook until fully browned and cooked through, about 7-10 minutes. Ensure the internal temperature of the turkey reaches 165°F.
Add the broccoli florets and shredded carrots to the skillet, cooking until they are heated through and tender, about 5-7 minutes.
Combine and Serve:
Reduce the heat to low and stir in the prepared teriyaki sauce, coating the turkey and vegetables evenly. Simmer the stir fry for a few minutes to allow the flavors to meld together.
Serve the ground turkey teriyaki stir fry over rice or your preferred base. Enjoy!
