Cooked spinach where it's just served as cooked spinach -- don't mind it in with other things in cooked dishes or raw (yes, I know.....)
Okra -- unless it's in soups
Canned asparagus -- my mother would trot this out about once every three months because she loved it and the rest of us hated it. She was always "surprised" but then got to eat it all herself. Considering how hard she worked, she earned this little indulgence (although I would have picked chocolate!!!!).
