Creating Chicken Zucchini Stir Fry is an easy process if you follow these steps:

1. Prepare the Ingredients: Slice the chicken breasts, zucchinis, and bell pepper. Mince the garlic and ginger.
2. Marinate the Chicken: In a bowl, combine the sliced chicken with 1 tablespoon of soy sauce, a pinch of salt, and pepper. Let it sit for about 10 minutes while you prepare the vegetables.
3. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat until shimmering.
4. Cook Chicken: Add the marinated chicken to the pan and stir-fry for about 5-7 minutes, or until the chicken is cooked through and golden brown. Remove the chicken from the pan and set it aside.
5. Stir Fry Vegetables: In the same pan, add the minced garlic and ginger. Stir-fry for about 30 seconds until fragrant, then add the sliced zucchinis and bell pepper. Cook for an additional 3-5 minutes until the vegetables are tender-crisp.
6. Combine Chicken and Sauce: Return the cooked chicken to the pan with the vegetables. Pour in the remaining soy sauce and sesame oil, mixing everything well. If using cornstarch for thickening, dissolve it in a bit of water and add it now.
7. Garnish and Serve: Cook for an additional 2 minutes, allowing the flavors to meld together. Serve immediately, garnished with sesame seeds and chopped green onions if desired.
