Creating Salt and Pepper Chicken is straightforward if you follow these simple steps:

1. Prepare the Chicken: Cut the chicken into bite-sized pieces and set aside.
2. Season the Cornstarch: In a bowl, combine cornstarch, salt, and black pepper. Mix well.
3. Coat the Chicken: Dredge each piece of chicken in the seasoned cornstarch until fully coated.
4. Heat the Oil: In a large frying pan, heat vegetable oil over medium-high heat until hot.
5. Fry the Chicken: Add the coated chicken pieces to the pan in batches, ensuring not to overcrowd. Fry until golden brown and cooked through, about 5-7 minutes per batch.
6. Remove and Drain: Using a slotted spoon, remove the fried chicken and place it on paper towels to drain excess oil.
7. Flavor the Chicken: In the same pan, add minced garlic, ginger, and sliced chili (if using). Stir-fry for about 30 seconds until fragrant.
8. Combine: Add the fried chicken back into the pan, tossing it with the garlic and ginger mixture.
9. Finish with Green Onions: Stir in chopped green onions and cook for another minute.
10. Serve Hot: Transfer to a serving platter and garnish with fresh cilantro if desired.
