My mom-in-law makes the sweet potato casserole topped with half marshmallows and half pecans. It is the only way to avoid full-on war at the holiday table. While I prefer the berry kind, for Thanksgiving I agree with you - it must be the jellied monstrosity with can lines so you know where to slice it. ;)

My moms side of the family will often have spagetti or pinto beans in addition to the regular Thanksgiving meal items. I have no clue why.
