Honestly, these turnips are so delicious on their own I don't think they need anything more than a quick steam and some butter, salt and pepper. I adore these things.
I agree. I would just throw the greens in for the last minute of steaming. That said, we are having ours raw tonight as part of a cold sesame noodle salad with the turnips, radishes, snow peas, chives and kohlrabi all cut into matchstick pieces.
