What Does Your Meal Include?

I know that there are a few thanksgiving items that are pretty much universal: pumpkin pie, cranberry sauce, turkey, and stuffing. However, the side dishes always surprise me when I find out what other people just have to have. Like I know green bean casserole with fried onions is a food that exist; but I have never had it. The same thing goes for sweet potatoes and marshmallows. What side dishes couldn't you live without at Thanksgiving?
