Eggplant is the one for me. I like almost every vegetable there is, including kohlrabi and artichokes, but eggplant has to really be disguised before I can deal with it. Even eggplant parmagiana isn't deep enough cover.
I'm not a fan of kohlrabi, but I don't mind eggplant.
Remember Beaver's Aunt Martha making eggplant for them while June was away?
