I hate stuffing and anything with baked-till-mushy veggies (green bean casserole, here's looking at you!). Also, I don't eat jello or meat, so there's that (though I did like ham or turkey when I was a kid; hated gravy, beef or gefilte fish -- yeah, my families celebrated a range of holidays). I go pretty nontraditional for the big holidays! My mom always made a cheesy potato casserole for holidays that I loathed to an amazing degree, but that was more of a family thing than a widespread tradition.
I am on team canned cranberries (whole berries, not jellied), though I made my own for the first time recently and loved it. It's kind of hard to find fresh cranberries here most of the year. Sweet potatoes without marshmallows, please.
