Mushrooms and olives - yup. I also don't like eggs - "themselves." Fine with egg on pad thai, and chopped up and mixed-in with rice, pepper and other stuff at hibachi tables too, though.
FYI: About hot dogs - years ago, I dated a girl whose Dad owned a meat processing plant. While chatting one day, she said: "IF you buy hot dogs, make sure to buy BEEF ones. And, no - you don't want to know why.." Caveat: I like hot dogs COOKED. At fairs, minor league sporting events, where they are BOILED - THAT is disgusting..
