1. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Sprinkle pork with pepper and salt. Add pork to pan; cook 3 1/2 minutes on each side or until the pork is done. Remove from pan; keep warm.
2. Add onions and next 6 ingredients (through garlic) to pan. Bring to a simmer. Cook 6 minutes. Arrange bok choy in a single layer over carrot mixture. Cover, reduce heat to medium, and cook 4 minutes or until bok choy is tender. Stir in cilantro and juice. Cut each pork chop into (1/2-inch-thick) slices. Spoon 1/2 cup vegetable mixture into each of 4 shallow bowls; top each serving with 3 ounces pork.
