Season pork chops with salt and pepper. Sprinkle thyme leaves over each, pressing, to help them adhere to the meat. Wrap 1 prosciutto slice around middle of each chop, like a belt; press ends to seal.
In a large nonstick skillet, heat oil over medium-high. Cook chops until golden brown and cooked through, 4 to 5 minutes per side depending on thickness. This may have to be cooked in two batches to avoid crowding.
