Sprinkle pork chops with seasoned salt. Spray 12-inch nonstick skillet with nonstick cooking spray. Heat over medium-high heat until hot. Add pork chops; cook until browned on both sides. Remove from skillet.
Add white sauce mix and milk to skillet; mix well. Cook over medium-high heat until mixture boils, stirring constantly. Stir in uncooked macaroni, green beans and cheese; mix well. Place pork chops over mixture.
Reduce heat to low; cover and simmer 15 to 20 minutes or until macaroni is tender and pork is no longer pink in center, stirring occasionally to keep mixture from sticking.
