There are some exceptions at times (like pickles), but for the most part, I hate the texture of crunchy vegetables. Particularly onions, broccoli, and cauliflower, but pretty much any veggie, is worse uncooked or undercooked imo. I hate most raw vegetables by themselves or in salads, but undercooked ones may be even worse because I was promised and expecting something cooked. Crunchy peppers or onions ruin a pizza as one example. Under-done carrots and potatoes in a curry, which I had yesterday, is another perfect example.
This may not be a universally unpopular opinion but I definitely feel like I’ve had a lot of people seem surprised by me not liking raw veggies.
I can tolerate a salad, but I agree with you especially about half-cooked vegetables. I even like to bring a whole head of cauliflower to a boil in enough salted water to cover, turn it off after it’s boiled a couple minutes and let it sit on the stove at least another 15 minutes (feel free to go do something else) or until you can stick a fork in deeply. Pour off the water, add whatever you like and eat it with a spoon.
