I'm not a fan of kidneys or green olives. I have tried for so long to just casually eat green olives, and every time it makes me gag. A nice cured black olive- no problem. Green olives- slimy grossy nastiness. Kidneys taste exactly like what I imagine excretion would taste like, which is probably the fastest way to ruin a dinner.

I can't think of any other foods I dislike. Apart from perfectly good foods prepared the completely wrong way. Like overcooked fish- crime against the fish AND humanity.
