I often find that they are often very large and thick when I buy my chicken breast cutlets in bulk. If yours are also large and thick, I suggest you cut them in half, lengthwise, to give you two ½ inch thick boneless-skinless chicken breast cutlets. You may also need a rolling pin or meat mallet to pound them out into a uniform thickness. I like buying bags of pre-portioned, individually sealed chicken breast cutlets (Perdue brand is a great one) as they are typically the perfect size to use.
