Sauce: in small bowl, combine soy sauce, sweetener, sesame oil, crushed garlic and 1/4 tsp onion powder. Mix well.

Spray wok or large skillet with cooking spray and heat over medium-high heat. Add chicken and sprinkle with garlic powder and 1/4 tsp onion powder. Add frozen veggies, sprouts and mushrooms. Cook and stir about 5 min, until chicken no longer pink and veggies are hot and tender.

Add zucchini noodles and scallions. Cook and stir until hot and slightly tender, about 3 min. Drain excess liquid. Add sauce and stir until evenly coated and mostly absorbed, about 2 min.
