Follow these simple steps to create your delicious Chicken Zucchini Stir Fry:

1. Prepare the Chicken: In a bowl, combine sliced chicken breast, soy sauce, and cornstarch. Toss to coat evenly and let marinate for about 10 minutes.
2. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
3. Cook Chicken: Add the marinated chicken to the pan. Sauté until it is golden brown and cooked through, approximately 5-7 minutes. Remove the chicken and set it aside.
4. Sauté Aromatics: In the same pan, add minced garlic and ginger. Sauté for 30 seconds until fragrant.
5. Add Vegetables: Toss in zucchini, bell peppers, and broccoli. Stir-fry for about 5 minutes until vegetables are tender but still crisp.
6. Combine Chicken and Sauce: Return the chicken to the pan. In a small bowl, mix oyster sauce and water. Pour the mixture over the chicken and vegetables, mixing well to combine.
7. Cook Further: Continue to stir-fry for an additional 2-3 minutes until everything is heated through and well-coated in sauce.
8. Season: Taste and adjust seasoning with salt and pepper as needed.
9. Garnish: Remove from heat and garnish with sliced green onions if desired.
10. Serve Hot: Serve your Chicken Zucchini Stir Fry immediately with your choice of rice or noodles.
