My family is from Ohio, very white and "traditional". We have turkey, of course, and at least one other meat, usually roast beef-ish. We have several thousand side dishes, including mashed potatoes (with homemade noodles), dressing, wild rice, yams w/marshmallows, green bean casserole with canned onion crisps/cream of mushroom soup, ambrosia, cranberry sliced from the can, fancy cranbery dressing, homemade rolls, creamed corn, oyster bake, lasagna, mac and cheese, several "exotic" salads - like tomato w/mozzarella, taco salad, etc etc etc.
When my sister married a vegetarian, it was no problem - there is enough variety in the side dishes that she & hubby had plenty to eat.
Oh, and of course there's dessert, too. Duh. If you want the list, it'll take several more paragraphs. I have turkey-shaped sugar cookies cooling in the kitchen ready to decorate.
The leftovers last for a long time.
