Whisk together garlic, ginger, soy sauce, water, apple cider vinegar, and sugar in a mixing bowl to create the teriyaki sauce.
Prep your ingredients by dicing onion, carrot, zucchini, and slicing chicken into strips. Season with salt and pepper.
Heat a cast-iron wok or large skillet over high heat, add oil, and stir-fry the chopped veggies for about three minutes until crisp yet tender.
Sear the seasoned chicken strips in the same wok over high heat until golden brown and fully cooked, about five minutes.
Add more oil to the wok, crack in the eggs, and scramble them. Then add the pre-cooked rice and stir-fry for three minutes.
Pour the teriyaki sauce over the rice mixture, add back the sautéed veggies and seared chicken, and toss everything together over high heat for a minute or two.
Serve the Teriyaki Fried Rice hot, optionally drizzling with ranch dressing and adding extra veggies on top.
