I can't think of many vegetables I don't like. I mean, I don't like onions on their own, like... onion rings etc. Red onion is okay in small amounts, but most of the time I'm served it the cook in question tends to put on too much for me. I really don't like asparagus. Brussel sprouts I can eat but I don't enjoy them on their own. Same for spinach. And as for tomato, it really depends on how it's cooked/prepared/served. I'm not sure of anything else, though, off the top of my head... Oh, if you count mushroom as a veg, I detest it. Bean sprouts and bamboo are things I find very bland and I dislike them based on that, but I can obviously still eat them.

I'll happily eat potato, carrot, peas, beans, cauliflower, broccoli, corn, peppers, parsnip, celery, lettuce, cabbage, lentil, rice... 'sall good. I miss my mum's cooking, she would make some great vegetable based foods. =x
The most commonly eaten veg at our place... probably carrots/peas/cauliflower (steamed veg packs), onions/peppers (fajitas) and carrot/broccoli/baby corn/sugar snap peas (stir fry).

The things I disliked as a kid but eat now? Not much, as I was always forced into eating most of my veg. I like peppers a whole lot more than I did back then. I tolerate spinach more, perhaps tomato too.

EDIT: Of my mum's cooking, I'd say my favourite non-standard thing would probably be carrot & parsnip mash. Mmmmmmm...
