Preparing Stir-Fried Chinese Garlic Chicken is a breeze with these easy-to-follow steps:

1. Marinate Chicken: In a bowl, mix the sliced chicken with 1 tablespoon of soy sauce, salt, and pepper. Let it marinate for about 10 minutes.
2. Prepare Sauce: In a small bowl, combine the oyster sauce, remaining soy sauce, cornstarch, water, and sesame oil. Stir well and set aside.
3. Heat Oil: In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat until hot.
4. Cook Chicken: Add the marinated chicken to the skillet. Stir-fry for about 5-6 minutes or until the chicken is cooked through and no longer pink.
5. Add Garlic: Add the minced garlic to the skillet and stir for about 1 minute, until fragrant.
6. Add Vegetables: Toss in the bell peppers and broccoli. Stir-fry for an additional 3-4 minutes, allowing the vegetables to become tender yet crisp.
7. Add Sauce: Pour the prepared sauce over the chicken and vegetables. Stir well to coat everything evenly.
8. Thicken Sauce: Continue cooking for another 2 minutes until the sauce thickens slightly and coats the chicken and vegetables.
9. Finish Cooking: Taste and adjust seasoning if necessary. Remove from heat.
10. Garnish: Sprinkle chopped green onions on top for added flavor and color.

These straightforward steps will guide you in creating a delightful dish that packs a punch of flavor.
