Creating the Savory Black Pepper Chicken Delight is straightforward and can be accomplished in just a few simple steps:

1. Marinate the Chicken: In a bowl, combine the cubed chicken, soy sauce, oyster sauce, and half of the black pepper. Mix well and let it marinate for at least 10 minutes.
2. Prepare the Vegetables: While the chicken marinates, slice the bell peppers and onion. Set aside.
3. Heat the Oil: In a large skillet or wok, heat olive oil over medium-high heat until shimmering.
4. Cook the Chicken: Add the marinated chicken to the skillet, stirring frequently. Cook for about 5-7 minutes or until the chicken is lightly browned and cooked through.
5. Add Aromatics: Stir in minced garlic and ginger, cooking for another 1-2 minutes until fragrant.
6. Incorporate Vegetables: Add the sliced bell peppers and onion to the skillet. Sauté for 3-4 minutes until the vegetables are tender but still crisp.
7. Thicken the Sauce: In a small bowl, mix cornstarch with a bit of water to create a slurry. Pour this into the skillet to thicken the sauce. Stir well.
8. Season to Taste: Sprinkle in the remaining black pepper and adjust salt as needed. Stir to combine thoroughly.
9. Garnish and Serve: Once everything is well mixed and heated through, remove from heat. Garnish with fresh cilantro or green onions if desired.
