If the turkey cutlets are thick, use a meat mallet or rolling pin to pound them to an even thickness of about ½ inch.
In a shallow dish, combine flour, salt, pepper, garlic powder, and paprika. In another shallow dish, beat the egg. In a third dish, place the breadcrumbs.
Dredge each turkey cutlet first in the flour mixture, then dip into the beaten egg, and finally press the cutlet into the breadcrumbs to fully coat.
In a large skillet, heat the vegetable oil over medium heat until hot but not smoking.
Add the breaded turkey cutlets to the skillet in a single layer, cooking for 4 to 5 minutes on each side until golden brown and cooked through.
Once cooked, place the cutlets on a plate lined with paper towels to absorb excess oil. Serve hot, garnished with chopped parsley if desired.
