Preheat the oven to 350 degrees F. Lightly coat a 2-quart baking dish with cooking spray.
Heat the canola oil in a large nonstick skillet set over medium-high heat. Add the ground turkey and onion. Cook, breaking up the turkey with a wooden spoon, until the turkey is cooked through, about 5 minutes.
Stir in the ginger and garlic, and cook for 1 minute.
Add the broccoli, red bell pepper and Napa cabbage. Cook until the vegetables are just tender, 4 to 5 minutes. Add the cooked rice and sauce, and stir to combine. Transfer the mixture to the prepared baking dish.
Cover and bake until heated through, about 15 minutes. Garnish with parsley and sesame seeds. Serve.
In a small saucepan set over medium heat, whisk together all of the sauce ingredients. Bring to a boil, then simmer until the sauce is thickened, about 5 minutes.
