Pound the chicken breasts to an even thickness using a meat mallet or rolling pin.
Set up a breading station with three shallow dishes: one for flour, one for beaten eggs, and one for breadcrumbs mixed with Parmesan cheese, garlic powder, salt, and pepper.
Dredge each chicken breast in flour, dip in egg, then coat in the breadcrumb mixture.
Heat olive oil in a skillet over medium heat and fry the chicken cutlets for 4-5 minutes per side until golden brown and cooked through.
Remove and place on a paper towel-lined plate. Garnish with parsley if desired. Serve hot.
