Parsnips, carrots(2:1 ratio), some quality olive oil and seasalt. Roast for like 40 min at 350. Sprinkle diced parsley on top as you serve. It's amazeballs. I have been roasting a crazy amt of veg lately and have been trying to branch out into things I didn't use to eat(parsnips, turnups, Brussel sprouts, etc). Roasting really creates a bunch of flavors you don't get out of them otherwise. Also, add other crap to them. Dried cherries, some shallots, etc. I sometimes get a decent wine and chicken stock/beef stock and reduce a cup of wine and 2 cups of stock to practically nothing, then drizzle over it.
You can do some minor things like that that can really make some amazingly delish stuff.
