Wash and chop kale. Mix chopped kale with fresh pears and tomatoes. Chill until ready to serve. In the meantime, combine canned pears, salt, and vinegar in a blender; cover and process until smooth. While processing, add olive oil in a steady stream. When ready to serve, pour dressing over kale mixture, tossing to combine. Stir in sunflower seeds and chick peas just before serving. Season with coarsely ground black pepper.
