Sweet vegetables. Anything that is unambiguously a savory main course plant, but has some sugariness to it. Peas, carrots, sweet potatoes, turnips, beets, etc. I can eat them, they’re just even more work than most food (I agree with the other commenter who said that food in general is just a chore like brushing your teeth, although really good food is basically a neutral experience for me, where the enjoyment is about worth the effort)

Oh I guess now that I think about it maybe there are exceptions, like I think a lot of people would consider red onions sweet but I am fine with those. I think it needs some sourness or sharpness to offset the sweetness, the problem is if it’s just sweet + savory and not much else.
