MIX all ingredients except cheese just until blended. Fold 2 (30-inch-long) sheets of foil lengthwise in half twice; crisscross pieces on work surface. Top with meat mixture; shape into 8-inch-round loaf.
USE foil handles to gently lower meatloaf into slow cooker, letting ends of foil hang over top edge of cooker; cover with lid.
COOK on HIGH 3 to 3-1/2 hours or until meatloaf is done (160ºF). Top with cheese. Let stand, covered, 5 min. or until cheese is melted. Use foil handles to lift meatloaf from slow cooker before slicing to serve.
