Heat a large skillet over medium-high heat. Add the cooking oil. Add the pork chops to the pan and brown on both sides, no need to cook all the way through, the slow cooker will do that. Set aside while you make the sauce.
Add the diced tomatoes, tomato paste, chicken broth, garlic, salt, pepper, thyme and oregano to the slow cooker. Stir until the tomato paste dissolves into the diced tomato juice. Add the onion and mushrooms, stir again. Add the pork chops into the sauce.
Cover and cook on low for 6-7 hours without opening the lid during the cooking time.
Serve over pasta or rice and enjoy!
