Place one chicken breast inside a gallon-sized zippered plastic bag and close the bag. Place it on your work surface and then use a rolling pin to hit the chicken breast, making it almost double in size as you pound. This helps make your chicken very thin and perfect for breading and frying. Once one chicken breast is done, remove it from the bag and add the next chicken breast. You can also use a meat mallet to pound chicken but I find this method to be much cleaner and neater.
