you do not list beets, I intensively dislike beets, beet tops and beet bottoms, I would have voted for beets, so I voted for okra but I am sure that is a technique issue
I like everything on the list but try as hard as I like I cannot like fennel. I want to like it, I try it a few times each year and I read it in recipes and want it, but when its in my mouth I always realise I just cannot like it. I hope that I will grow to like it one day soon!
I used not to like okra though, until I had some beautful curried okra that changed my mond for ever. Any vegetable cooked badly is always off putting though.
I vote for celery. I realize it's a major component in just about anything I cook, and I never omit it to satisy my taste...but I don't like it. More often than not, I find it bitter, with the exception of the very very tender center, tiny stalks. Those, I love.
Now, if you'd put zucchini on that list, I'd have voted for that, instead. I really have no strong objections to any vegetable.
Okra and big fat lima or butter beans are the only veggies I can think of that won't cross my lips! Anything else I have no problem with. Have to credit my Mom with cooking veggies properly & my late ex-MIL with introducing me to artichokes.
