I think compared to me, everyone else is picky.
Seriously, I eat just about everything. I might need a moment to get used to something new (read: wierd), but then I quickly start appreciating it.
Brussel sprouts, butterbeans, beets? Sure. I'll actually eat a can of pickled beets by itself in a sitting. Same with palm hearts, black olives, and artichoke heart quarters. No pickle is safe in my house, including pickled okra and cauliflower. I eat sardines and fish steaks for breakfast some days. Salted raw turnip is like a delicacy. Potatoes, too.
There's a spanish manufacturer that cans squid, octopus, and abalone much like sardines. I love those when I can find them. Gravlax? Love it. Frozen mussels? I actually found and ate microwaveable ones. Not bad.
Anybody feelin' funny in the tummy yet? :-D
