Any guess? I would think that green bean casserole with the crispy, french fried onions on top would be the favorite Thanksgiving side dish because it seems to be everywhere, but it's not what most people pick. (Does anyone know if those things are actually onions?) Apparently the green bean casserole is common, but not necessarily that popular.
The top Thanksgiving side dish here is actually something that can be made to be super healthy. Or we can cram enough fat and calories into it that it really becomes nice and fattening and Thanksgiving-y. Here it is.
