Tenderize the steaks by pounding on them with a meat tenderizer. Lightly beat the egg(s) with a fork and add salt, garlic powder and chopped parsley. Mix. Pass the meat through the egg mixture, and then through the bread crumbs. You can use either plain bread crumbs, or "Italian" style. Coat well.
Fry in olive oil until done, usually a couple of minutes on each side. You can also bake the milanesas on the oven - for a less fatty alternative. If you fry them, make sure to use a few paper towels to drain the oil.
