In a large cast-iron or other heavy skillet, heat butter over medium heat. Brown pork chops on both sides; remove from pan, reserving drippings.
In same pan, saute vegetables in drippings until lightly browned. Whisk together soup and water; stir into vegetables. Bring to a boil. Reduce heat; simmer, covered, just until vegetables are tender, 15-20 minutes.
Add chops; cook, covered, until a thermometer inserted in pork reads 145°. Remove from heat; let stand 5 minutes. If desired, sprinkle with pepper and parsley.
