Start by preheating your oven to 400 degrees and spray a baking pan with non-stick spray. Once done, add all chicken meatball ingredients to a large mixing bowl. Using your hands, combine well. Using a scoop, spoon or just eyeballing it, roll 25 - 30 small meatballs and place on your prepared baking sheet. Bake for 25 - 30 minutes.
While your meatballs are cooking, start preparing your rice. Add chicken stock to a large pot and follow rice box instructions. When your rice is cooked, remove from heat but keep covered until the rest of the meal is prepared.
In a large skillet, add a tablespoon of olive oil and heat over medium high heat. Add in sliced zucchini, carrot straws and sliced purple cabbage. Cook and stir until just tender, about 4-6 minutes. Remove veggies from skillet and transfer to a medium bowl.
Using the same skillet, combine your soy sauce, brown sugar, honey, vinegar, sesame oil, sriracha and seasonings over medium heat, stirring until the sugar has dissolved.
In a small bowl, add 1-2 tablespoons of water and the cornstarch and whisk to dissolve. Whisk the cornstarch mixture into your teriyaki sauce and increase the heat to medium high. Bring to a low boil and continue stirring as the sauce should now begin to thicken a bit.
When you remove your chicken meatballs from the oven, add them into your skillet and toss to coat. Serve your teriyaki meatballs along with the rice and mixed veggies. Sprinkle with green onion and toasted sesame seeds.
