Place chicken into a freezer type bag and pound until about ½” thick. Pound each piece until ½ inch thick. Sprinkle with salt and pepper.
Set up a dredging station, place each of the following next to each other beginning with the flour.
Mix flour with garlic powder and Italian spices, place on a plate or shallow dish for dredging.
Place whisked egg into a shallow bowl and set next to flour.
Mix breadcrumbs and Parmesan cheese and place into another shallow dish or plate next to the egg.
Dip the chicken pieces, one at a time into the flour, then egg and then the Parmesan breadcrumb mixture.
Heat a pan large enough to hold all the chicken pieces so they don’t touch, add olive oil and then the chicken, don’t overcrowd the pan or the pieces won’t brown. Cook until lightly browned then set aside, if needed, and cook remaining pieces.
When finished browning the chicken you can add them back to the pan or place on a sheet pan and top with a little marinara sauce and mozzarella cheese, broil until cheese has melted.
