Cut the tenderloins into 4 to 6 even slices. Place plastic wrap over pork; pound to an even thickness using a meat mallet or rolling pin. Rub each piece of pork with orange zest. Then sprinkle both sides with ginger, salt and pepper. Set aside.
Combine the salsa ingredients in a bowl. Toss, add salt and pepper, to taste. Set aside.
Heat the olive oil in a large skillet over medium-high heat. Add half of the pork; cook 3 to 4 minutes on each side (or until done). Remove the pork from the pan; repeat with the rest of the pork. Serve topped with the mango salsa!
