Anything pickled .... eeewwww yuck. Also anything over-cooked ... too mushy and slimy, and all the good stuff is cooked out so what's the point of eating it?
There are things I haven't tried that look or sound weird -- okra comes to mind -- but I'll try anything once. I don't care for raw mushrooms (or canned, for that matter), raw celery, olives (but love olive oil), lima beans (can't stand the texture). Don't really care for canned veggies, seems to dull the flavor and mess up the texture.
Beets, Okra, eggplant (sorry LindaT). I keep thinking I would like eggplant if I could cook it properly, but I've never been successful.
Never tried parsnips or rutabaga.
LOVE most other veggies, lucky that way.
I haven't eaten lima beans since my mother stopped forcing me. My dh hated lima beans as a child too, so we have never bought them. When ever my 7 year old is complaining about trying some new food, dh always tells him that it could be worse, it could be lima beans and liver.
I really, absolutely, can even stand the smell of cucumber. I hate most veggies but can disguise them enough to get them down but not cucumber. If it is in a salad I can't touch the salad it is contaminated!
Someone mentioned parsnips, they are super carrots, oh just nasty.
Loathe Swede (Rutabaga I think you Yanks call it) and turnips and parnips and kohlrabi. All soemwhat sweet - not fond of yams or sweet potatoes either. Or cooked celery - raw is fine. Raw carrots better than cooked too.
