First prep all vegetables and dice the chicken. Set aside.
In a small bowl, add all sauce ingredients and mix until well blended. Be sure the brown sugar gets dissolved. Set aside.
Coat a large nonstick wok or pan with cooking spray. Add chicken and cook stirring often, until cooked through and white inside. Remove to a plate.
In the same pan, coat with more cooking spray and heat 1 tablespoon of oil. Add onions, broccoli, zucchini, red bell peppers, and water. Sauté over medium-high heat for 3-5 minutes until broccoli is soft. Add cabbage and sauté another 2 minutes until cabbage is soft. Turn down to medium heat, add cooked chicken and sauce. Stir-fry for about 2 minutes until all heated through. Stir constantly to blend everything.
Store any leftovers in the fridge for a few days.
