Late or no, the traditional Thxgiving meal is similar to Christmas dinner - Stuffed turkey, mashed potatoes, some kind of yams (candied or otherwise at Thx only), brussell sprouts and/and other veg, cranberry jelly, turkey gravey... and pumpkin pie. People vary it as they like, of course, but that's what's traditionally expected at Thxgiving.
My favourite stuffing includes sausage meat and pine nuts - sometimes chopped water chesnuts for the crunch. MIL made the dinner yesterday and served Stove Top! Inside the turkey, crazily enough. Okay, that's interesting
And barely enough to go around. Everybody knows you have to make DOUBLE the stuffing!
Edit: And I remember eating all this well before the 80s, when I was a child, so don't know about ehBeth's dates. I was a kid in the 60s.
