While the kale is cooking, start preparing the pork chop so that both are ready at the same time.
In a medium skillet, heat 2 teaspoons olive oil over low heat. Add garlic; cook, stirring often, until very tender but not browned, about 10 minutes.
Add kale, and season with salt and pepper. Add 3 tablespoons water. Cover; cook, tossing occasionally, until kale is wilted and tender, 10 to 15 minutes.
Rub 1/4 teaspoon each coarse salt, ground pepper, and dried sage on both sides of pork chop.
Heat 1 teaspoon olive oil in a small nonstick skillet over medium heat. Add pork chop; cook until browned but still juicy, about 3 minutes per side. Transfer to a serving plate.
Add lemon juice and remaining teaspoon oil to skillet; bring to a boil. Pour over pork. Serve with kale and a lemon wedge.
If the kale starts to appear dry as it cooks, add a bit more water to the skillet.
