In a shallow dish combine flour, salt and pepper. Dip pork slices into flour mixture, turning to coat. Coat a heavy large skillet with cooking spray. Add 1 tablespoon of the oil to skillet; heat over medium-high heat. Add four pork slices to hot oil; cook 3 to 4 minutes or until pork is slightly pink in center, turning once halfway through cooking time. Transfer pork to a serving platter; cover with foil to keep warm. Repeat with the remaining 1 tablespoon oil and the remaining four pork slices.
