I know it is not root vevies, but I love corn on the cob done on a BBQ... it's yummy :)

My favorite fall/winter salad consists of roasted beets (roast in their skins and peel once they've cooled), goat cheese, and toasted pumpkin seeds on a bed of arugula. Yum!

Also delicious and beautiful if you live in a place where you can get good avocados in the winter (I don't anymore) is a composed salad of sliced roasted beets (red and yellow, if you can get both) and sliced avocado with a little citrus zest. It's shocking how nicely the silkiness of the beets and avocado combine.

I usually will roast slices of pumpkin, carrots, potatoes and sweet potato layered alternatively in a Dutch oven with some salt, pepper and olive oil. I serve it with a sauce whipped up of Creme Fraiche Parvé, plain yoghurt, cognac, sprinkle of nutmeg, cardamon, cinnamon, ginger and honey.

Or soup! pumpkin, carrots, parsnip, potatoes sauteed with shallots and garlic, then purred in a blender with some white wine and basil, parsley, coriander salt and pepper.

or a curry stew! mushrooms, pumpkin, squash, sweet potato, yams,red potatoes,parsnip, ginger.....
