Plan B, prepare all food as expected, puree and place into a carboy so you can enjoy Thanksgiving in a bottle by the time your recover. Not sure how Turkey would ferment but I bet a cranberry sauce stuffing ale would work.
I assume it tastes like turkey and gravy? What in the world makes it taste like it that is not actually it. I wouldn't want that ever let alone for Thanksgiving.
The guy is sick already, he probably just threw up.
