In a bowl, combine chicken pieces with freshly ground black pepper and a pinch of salt. Let it marinate for at least 15 minutes.
Heat the vegetable oil in a large skillet over medium-high heat. Add the marinated chicken and stir-fry until chicken is browned but not fully cooked. Remove and set aside.
In the same skillet, add the onion and green bell pepper. Sauté for about 2-3 minutes until slightly softened.
Add the minced garlic to the skillet and sauté for about a minute until fragrant.
Return the chicken to the skillet. Add the soy sauce, oyster sauce, and sugar to the mixture. Stir well to coat the chicken and vegetables.
In a small bowl, mix the cornstarch with water to create a slurry. Pour this mixture into the skillet and stir continuously until the sauce thickens.
Adjust seasoning with salt if necessary. Cook until the chicken is fully cooked and tender, about 5 more minutes.
Garnish with chopped green onions before serving.

Use pre-cut or pre-trimmed chicken thighs to save prep time. Toast and grind your black pepper in batches for efficiency.
