I have been making the cauilflower mash, instead of mash potatoes and it is really good. I just boil cauilflower until soft, add low fat milk, light butter, season to taste with salt and pepper and mash until creamy just like mash potatoes

I've been grating the carrot and parsnip when I make soup ... and sauting them in a skillet along with finely chopped onion and thinly sliced celery before adding them to a pot of boiling water or broth and other ingredients. There is something about cooking the veggies down a bit before adding to the pot that really brings out a lot of great flavor.
