In a 12-inch nonstick skillet, heat reserved oil from sun-dried tomatoes over medium-high heat. Stir in tomatoes, garlic, 1/2 teaspoon each of the salt and pepper and 1 teaspoon of the thyme. Cook 2 minutes; transfer tomato mixture to medium bowl. Stir in bread crumbs and cheeses; set aside.
In thick side of each pork chop, cut a slit about 2 inches deep and 3 inches long to form a pocket (do not cut in half). Spoon 2 tablespoons tomato-cheese mixture into each pocket; pinch edges of pork to seal. Sprinkle pork with remaining 1/2 teaspoon each salt and pepper. Cover; refrigerate 1 hour.
Heat oven to 450°F. In same nonstick skillet, heat 1 tablespoon of the olive oil over medium-high heat. Cook 4 pork chops in oil 4 minutes, turning once. Place pork on cooling rack in 15x10x1-inch pan. Repeat with remaining 1 tablespoon olive oil and 4 pork chops. Bake 25 minutes or until meat thermometer inserted in center of pork reads 145°F.
Meanwhile, in small bowl, mix broth, lemon peel, lemon juice, mustard and remaining 1 teaspoon thyme. Pour into skillet, stirring to loosen browned bits. Heat to boiling; reduce heat. Simmer 7 minutes or until slightly thickened. Stir in butter; cover to keep warm. Serve pork chops with sauce.
