Creating Chicken, Broccoli & Mushroom Stir-Fry is a straightforward process. Follow these steps to achieve a delicious result:

1. Prepare the Ingredients: Slice the chicken, chop the broccoli, and slice the mushrooms and bell pepper. Mince the garlic and ginger.
2. Marinate the Chicken: In a bowl, combine the chicken strips with 1 tablespoon of soy sauce and a pinch of salt and pepper. Allow it to marinate for about 10 minutes.
3. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat until shimmering.
4. Cook the Chicken: Add the marinated chicken to the skillet in a single layer. Sauté for 5-7 minutes, or until the chicken is cooked through and golden brown. Remove from the skillet and set aside.
5. Sauté the Vegetables: In the same skillet, add the minced garlic and ginger. Sauté for about 30 seconds until fragrant. Then, add the broccoli, mushrooms, and bell pepper. Stir-fry for 3-4 minutes until the vegetables are tender-crisp.
6. Combine Chicken and Vegetables: Return the cooked chicken to the skillet with the vegetables. Pour in the remaining soy sauce and oyster sauce (if using). Stir to combine.
7. Thicken the Sauce: Add the cornstarch mixture to the skillet and stir well. Cook for an additional 1-2 minutes until the sauce thickens slightly.
8. Serve: Remove from heat and serve immediately over cooked rice or noodles.
