Heat olive oil in a skillet over medium-high heat. Season pork chops on both sides with salt and pepper. Brown pork chops on each side, about 2 minutes. Transfer to a plate. Reserve pan drippings.
Add the onions, garlic and capers to the pan. Cook 1 minute. Stir in tomatoes and kale. Cook just until the kale starts to wilt, about 2 minutes.
Return the pork chops to the pan. Spoon a little of the tomatoes and kale over the top. Cover and cook in the preheated oven for 15 - 20 minutes or until pork chops are cooked through.
Season to taste with salt and pepper. Transfer pork chops to a serving platter. Spoon the tomato mixture over the top. Serve.
