How bad are they for you? I've already had dinner but was feeling pekish so i skinned and cut up 3 parsnips and put them in a bag put a little vegetable oil in shook up the bag layed them out on a baking tray and they are currently in the oven. So how bad are they for me, many calories? Can you eat parsnips raw, like carrot, because they are like carrots? Can you roast carrots?
