A fish sandwich doesn't have to be deep-fried to be delicious. Try our healthy crispy fish sandwich recipe with a tangy, zesty pineapple slaw. It's worth taking the extra minute to chop pineapple slices instead of using crushed pineapple, which is too small and disappears into the slaw. Store-bought shredded cabbage-carrot mix saves time. Look for it in the produce section.
