Boiled okra. My mom used to put it in the collard greens (which we had at least twice a week) and the black-eyed peas (also two or three times a week). The happiest day of my gastronomical life* was when I left home and knew that I could now eat both collards and black eyed peas and never, ever again be forced to allow boiled okra to pass my lips.
I hate okra. If it were up to me, every field that had ever grown okra would be salted so that nothing would ever grow there again!
Did I mention that I loathe and despise okra?
*happiest until the day I discovered sushi. To quote the web comic
