pineapple on pizza
fruit in a salad
salt and vinegar chips
tomatoes (I like sauces but that's it)
anything hotter than a weak medium.
I have that gene that makes Cilantro taste like soap.
Don't like ham and I'm not that big on most deli-meats (except like pepperoni and salami and other kind of spicy meats).
Dislike tuna, unless it's raw.
Not big on some weird fancy cheeses. Don't like whatever that cheese is that generally goes in lasagna. Don't like blu cheese.
Not a fan of olives but I'll usually eat them.
I'm sure there are other things.
I used to be a pretty picky person, but I've always tried to expand my pallet and I'm probably no longer someone who is especially picky.
