Ham is great too, cookie! And with all the delicious-sounding sweet potato dishes folks have offered here- I'd be tickled & fit as a fiddle with a meal of only ham and a sweet pot. casserole from among those here! winks- k.
I like that green bean casserole dish you mentioned to it is really good... Cookie 
The Campbell's Canned Soup green bean casserole with those funky canned Durkee fried onions is an American Thanksgiving classic! Even when I have worked at ultra-fancy joints that did everything from scratch using persnickety homemade, high-end ingredients, we did a version of it for most holidays. And even in remote Alaska amongst the Eskimo populations that live in very remote villages- they order the ingredients for this and other turkey-day standards very early- like in AUGUST, just to make sure they have them by the time the holidays roll around! When one visits the natives- it's considered polite ettiquette to always have a food gift to present- and canned cranberry sauce and other fruits (especially madarin oranges and cherries) were ALWAYS absolutely TREASURED by these wonderful folks!
You are right it is an American Thanksgiving classic that's for sure!! I Love the whole cranberries mm so good! Cookie
