Place the steaks between two sheets of parchment paper and pound them to about ¼-inch thick. Season generously with salt and pepper.
Dip the seasoned steaks into flour and shake to remove any excess.
Beat the eggs in a shallow bowl and place the Panko breadcrumbs in a second shallow bowl.
Dip the floured steaks into the egg, shaking off any excess, and then place them into the bowl with the breadcrumbs. Press the steaks into the breadcrumbs on both sides so they are fully covered and well breaded. Set aside.
Heat the oil in a large skillet over medium-high heat and cook one or two steaks (depending on the size), for 3-4 minutes on each side until crispy and golden brown. The steaks should cook fully if pounded thin. Continue with the rest of the steaks. Add more oil to the skillet if needed.
