Hrm. I think I'm lucky, because though there's a whole list of vegetables I don't like (including collard greens, turnips, radishes, cauliflower, brussel sprouts, and eggplant) there's still a whole list of them that I do.
Soup is a good idea. I know you said you didn't like hiding them in other foods, but spinach I've found to work well in lasagna. Tomato sauce is in there too. I never did get into the mashed cauliflower thing. It's not mashed potatoes, I'm not falling for it.
Or you can make dessert out of it. There's pumpkin pie, and sweet potato pie. I don't like sweet potato pie so much as pumpkin pie, which I do kind of love.
If you really don't like veggies, I suggest making sure you get a good variety of fruit in, then. It'll be higher in calories, but it has good fiber and nutrients and vitamins. You might even want to research some online about what fruits and veggies are rich in what nutrients, to make sure you're getting a good mix in.
And do try vegetables again now and then, in different ways. I used to hate spinach. Then I realized I actually loved it raw, in salads. And now, five years later, I sort of like it cooked, in moderation, when it's just a component of other dishes. Raw carrots I'm not all that fond of (too many bad memories on Weight Watchers as a kid), but I like them cooked. For a long time I hated asparagus, then suddenly one time I tried it, and I liked it.
Then there are things that I try and still hate. I don't think I will ever like brussel sprouts, though every 2-3 years, I gamely give it another try. You never know.
