Heat olive oil in a large skillet over medium-high heat. Place pork chops, lemon side up in the hot oil; cook 6 minutes. (Reduce heat if prosciutto is browning too quickly) Carefully turn pork chops over with tongs or a thin metal spatula and cook 2 to 3 minutes more, until an instant read thermometer inserted in the center reads 145˚F and prosciutto has caramelized.

Arrange pork chops on serving platter or place one on each of 4 dinner plates; spoon sauce over each chop and garnish with finely chopped sage; serve immediately.
