To prepare pork, place chops in a shallow dish; drizzle evenly with Worcestershire. Combine salt, sage, and black pepper in a small bowl. Reserve 3/4 teaspoon salt mixture. Add walnuts to remaining salt mixture; toss well. Press walnut mixture onto both sides of pork chops. Cover and refrigerate 30 minutes.
Cook bacon slice in a large nonstick skillet over medium heat until crisp. Remove bacon from pan; crumble. Add pork chops to drippings in pan; cook 1 1/2 minutes on each side or until lightly browned. Add 1/4 cup chicken broth to pan. Cover, reduce heat, and cook 6 minutes or until desired degree of doneness. Remove pork from pan.
To prepare rice, heat a large saucepan over medium heat. Coat pan with cooking spray. Add onion and next 3 ingredients (through garlic) to pan; cover and cook 5 minutes or until onion is tender. Stir in reserved 3/4 teaspoon salt mixture, chard, mushrooms, and apple. Cover and cook 5 minutes or until carrot is tender. Stir in rice and 1/2 cup broth. Bring to a simmer; cook, uncovered, 5 minutes or until liquid is absorbed. Stir in bacon. Place 1 cup rice mixture on each of 4 plates; top each serving with 1 pork chop. Drizzle each serving with pan drippings, and sprinkle each with 1 tablespoon parsley.
