4 bone-in pork loin chops, 1 1/4-inch thick3 tablespoons crumbled feta cheese2 tablespoons chilled basil pesto1 tablespoon toasted pine nuts 1 teaspoon ground black pepper1 teaspoon dried oregano1 teaspoon minced garlic1/2 teaspoon red pepper flakes1/4 teaspoon ground thyme1/2 cup vinegar (optional)
1. Preheat oven to 375 degrees F (190 degrees C).2. Mix feta cheese, basil pesto, and pine nuts in a bowl. Use the tip of a sharp boning or paring knife to cut a 3-inch slit in the side of each pork chop, 2 inches deep and 1/4-inch away from the bone, to make a pocket for stuffing. Stuff pork chops with pesto filling and secure with toothpicks.3. Mix black pepper, oregano, garlic, red pepper flakes, and thyme in a small bowl; rub both sides of each chop with the spice mix. Place chops into a shallow baking dish.4. Bake in the preheated oven until chops are browned and stuffing is hot, about 40 minutes. An instant-read meat thermometer inserted into the center of the stuffing should read 145 degrees F (63 degrees C).5. (Optional) Brush chops with balsamic vinegar and bake until vinegar forms a glaze, another 5 minutes.
