Combine the breadcrumbs, oregano, Parmesan, salt and pepper on a wide plate. Set a cutlet on the breadcrumbs and coat on both sides, firmly pressing on the breadcrumbs to help them adhere. Set coated cutlet on a clean plate. Repeat with remaining cutlets.
Heat the oil in a large, non-stick skillet set over medium to medium-high heat. Add the pork and cook 3 to 4 minutes per side, or until golden brown and cooked through. Serve cutlets with the marinara sauce.
Note: Tenderized pork cutlets are available in our meat department. Marinara sauce is available in the aisle other canned and bottled pasta and tomato sauces are sold.
