Guess I'm in the minority. I'm a "liver lover." Except for our youngest son, I'm the only one in the family who likes it.
When Ryan was in high school and everyone else in the family had outside commitments at dinnertime, he'd come to me and ask, "Mom, can you and we have liver and onions tonight?" Didn't have to ask me twice.
As far as other "dislike" foods, I can't really bring anything to mind. Don't particularly care for Brussels sprouts, but I really want to try some ultra-fresh ones that haven't been cooked to death. As a child, I never bought the "they're only little cabbages" line and I've always like cabbage in any form.
I've discovered that, as I age, my tastes change. I used to actively dislike asparagus then, all of a sudden, a friend prepared an asparagus dish (using canned, of all things) and I loved it. Ever since then, asparagus and I have been good friends.
All boils down to I like most everything...so far.
