Many home cooks are comfortable with spinach but are intimidated by the unfamiliar variety of other cooking greens: chard, mustard, turnips, collards, kale and more. But it doesn't matter much which you include in a given dish: they're all good, and they all cook quickly. This preparation is dead easy. You first steam the kale with butter (you could use olive oil, but here it just isn't the same), white wine (water is almost as good) and garlic, until it's just about done. At that point you top the greens with a fillet or two of white fish and continue to steam until the fish is cooked through. Timed correctly, the greens will be tender and bright green and the fish moist. The juices from both will have combined with the butter, wine and garlic to produce a sauce that is great with rice or bread.
