Season the pork chops on both sides with freshly ground black pepper, paprika and salt; set aside.
In a large saucepan over medium heat, add oil. When it gets hot, working in batches, add the seasoned pork chops and cook until brown, about 3 minutes per side.
Transfer the chops to a plate and remove the fat in the pan with paper towels.
Add chicken broth, Worcestershire sauce, brown sugar and tomato paste to the saucepan. Stir well and return the pork chops back to the pan including any accumulated juices; spoon sauce over.
Cover, reduce the heat to medium-low, and simmer for 45 minutes. During cooking time, flip them over, spooning sauce on top.
15 minutes before the cooking time is up, place a lemon slice on each pork chop, spoon more sauce over and press down gently on the lemon slices to extract some juice.
Cover again and simmer for the remaining time; press down on the lemon as well as basting while cooking. If the sauce is not thick enough, mix 2 tsp. cornstarch in ½ cup cold water and add to the sauce.
Served with mashed potatoes and steamed veggies.
