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

1. Prepare the Chicken: Cut the chicken into bite-sized pieces and place them in a bowl.
2. Marinate: Add salt, pepper, garlic powder, onion powder, and paprika (if using) to the chicken. Mix well and let it marinate for 10-15 minutes.
3. Coat the Chicken: In a separate bowl, add the cornstarch. Dredge the marinated chicken pieces in the cornstarch until fully coated.
4. Heat Oil: In a large pan or wok, heat enough cooking oil over medium-high heat for frying.
5. Fry Chicken: Carefully add the coated chicken pieces to the hot oil in batches, ensuring not to overcrowd the pan. Fry until golden brown and crispy, about 5-7 minutes.
6. Drain Excess Oil: Use a slotted spoon to remove the chicken and place it on a plate lined with paper towels to drain excess oil.
7. Add Garnishes: In the same pan, add the chopped green onions and sliced chili peppers (if using). Stir-fry for about 1 minute until fragrant.
8. Combine: Add the fried chicken back into the pan with the green onions and chilies. Toss well to combine and heat through.
9. Finish: Remove from heat and let it rest for a minute before serving.
