For me pickles would be at the top of the list. Why?

Tomatoes are meh for how they are treated as an MVP.

Onions both taste and smell horribly. If I had to get rid of any one veggie that'd be it.

Corn would be second.

Tomatoes are a fruit.

Love pickles.

Pickles (cucumbers) are fruit, too, technically. They're my favorite though! (And I don't know a soul who consider them fruit.) Prefer pickles over their common pre-evolution, but often buy and order/add them when eating out as well.

Potatoes, shrooms, and carrots would round out the top 5. Used to enjoy hot/spicy peppers but can't really do them anymore.

Mostly indifferent to most other veggies.

On topic: Onions are definitely dead last. I hate them. Like mayonnaise as a condiment (gag), I don't get how onions are enjoyed. People always say it adds flavor... Uh, yeah, if you like disgusting as a flavor, I guess. If they're diced into minuscule pieces for chili and such, that's okay, I can largely ignore (not taste) them, but otherwise, no. Garlic would be second to last.

Not a big fan of broccoli. It’s not versatile. I’ld rather Brussels sprouts and asparagus before it. Might be the only vegetable I don’t like.

I love all vegetables apart from beetroot.

I forgot about mushrooms. Fuck mushrooms.

I was anti onions until a few years ago then I started cooking with them and now consider them a good addition.

Eggplants and mushrooms are not veggies, but they're the only produce I won't eat.

Cooked onions chopped small are a good flavor. They're not meant to be eaten like apples for pete's sake

I dislike tomatoes but I will sometimes eat them. They're not awful

You guys and your definitions, lol. You really need to give up on what is and isn't a vegetable, and what is and isn't a fruit, etc. etc. ad infinitum. Everybody knows that a tomato TECHNICALLY isn't a vegetable, but nobody cares. To most people it is a vegetable. As are cucumbers.

It just doesn't work in other parts of the language. Answering the question "does it taste fruity?" gets pretty fucking difficult if you have to include cucumbers, tomatoes, etc. in your answer. To most, fruits are sweet. And I see nothing wrong with that. If it actually mattered or helped in any way to get the definitions botanically correct, then I'd be all for it, but apart from knowing a bit of trivia it is useless information.

Tomatoes are fruitier than avacados. (and both are fruit) Never heard cucumbers were a fruit, to me that’s always been a vegetable…

And mushrooms aren’t even a plant, so neither fruit nor veggie. Whole other kingdom of life, fungi.

To answer the question, I’d echo some here that I struggle with onions (but try to accept / eat them sometimes, they’re super healthy). On the other hand I love garlic. I think I’m okay with most veggies.

Onions are amazing. How dare y'all!

I like all vegetables tbh. I used to not care for eggplant but love it now.

I don't get the onion hate. LOVE onions.

I'm liking more and more vegetables these days which is good.

Least liked? Maybe the Asian greens like Buk Choy, Choy Sum etc

This is one of the things I make the most

Bottom layer broccoli/onion (both cooked beforehand - though not cooking the onion beforehand is an alternate version that also works and how I originally did it before switching to cooked)
Rice and cheese layers (I usually just cut cheese cubes but I think it would be ok shredded)
Cook in oven enough for cheese to melt
