What is a traditional thanksgiving meal obviously is personal to your own family history - could be jello salad, could be yams with marshmallows or maybe creamed peas. Likely it includes turkey, stuffing, potatoes and pumpkin pie. But are these foods "authentic" to the original harvest feast held by the pilgrims?
Well, we can definitely rule out the jello salad!
(looks good, yes? Are the square shapes cheese?)
It is likely that wild fowl (turkey, pheasant, goose?) was part of the meal, as well as seafood, shellfish, greens, dried beans, dried berries and corn. Pumpkin and squash would have been available but pumpkin pie would have been unlikely as there was no access to the ingredients for the crust. Cranberries might have been included but no sugar! Those pilgrims were hardy stock.
I'm thinking of avoiding the entire "traditional" and going the seafood route.
Imagine the table set with a whole fish to carve .... what would your guests think?
