Preheat the oven to 375℉ (190℃).
Salt pork chops, then season both sides with Italian and Creole seasoning. You can use one or both; I used both.
Place pork chops on a board or flat surface. Cut a slit or pocket about ¾ quarter of the way through each piece; try not to cut all the way through. Generously season inside the pork chop.
In a large skillet or frying pan, add olive oil and garlic, sauté over medium heat for about a minute. Then add the mushrooms and bell pepper and continue stirring for 2-3 minutes. Finally, add spinach and stir frequently until wilted and cooked, 2-3 minutes. Set aside.
Stuff slit pork chops with the mushroom, spinach, and bell pepper mixture. Add one or two slices of cheese per pork chop if desired.
Thread pork chops closed near the openings with toothpicks to secure them. If some of the filling comes out, just tuck it back in.
Heat an oven-proof skillet over medium heat with a tablespoon of oil. Sear the pork chops on both sides for 3-4 minutes each or until golden. Using tongs to flip them over carefully makes it easier to keep the stuffing inside.
Place the skillet in the oven and bake the pork chops for 14-16 minutes or until the internal temperature registers 145℉ (65℃) on an instant-read thermometer inserted into the thickest part of the pork. Pork will continue cooking an extra 5℉ while resting.
Transfer the pork chops onto a serving platter and cover with foil. Let them rest in a warm place for 5-10 minutes before serving. Carefully remove and discard the toothpicks.
Serve drizzled with the juices from the skillet.
