You could make a lovely, summery kind of 'slaw...with carrot and maybe some sesame seeds or sunflower seeds, and a lemon-olive oil dressing rather than a heavy, creamy one. Apple and cabbage are really nice together, though it sounds strange...a saute of finely-sliced cabbage, apple, red onion (add a little sugar or honey and a splash of apple cider vinegar) goes really well with pork. Cabbage is nice to add to soups as well - there are lots of things you can do with it!
