Cut the chicken breast into bite-sized pieces.
Marinate the chicken breast with soy sauce, minced garlic, and black pepper for 10 minutes.
Coat the chicken breast evenly with potato starch.
Add a generous amount of cooking oil to a pan and heat over medium heat.
Cook the chicken breast until golden brown, as if deep-frying.
Place the cooked chicken on a paper towel to drain excess oil.
Lightly sprinkle black pepper over the finished chicken breast.
