To be fair; extant diaries of colonists present at the first Thanksgiving do not list turkey among the catalogue of victuals. There were no deserts of any kind, or fancy beverages either. The meat the colonists brought to the feast was only duck, which would have required about 40% less work to hunt than the wily turkey; an energy savings that would have been of great import to the decimated colony. Other fare was squash, maize and nuts.Apparently neighboring natives had been invited in hopes they would bring food with them, and also as a desperate bid for mercy. They came expecting a fully catered affair, and were shocked to find a small band of pot-lucking colonists (50 of the original 200) on the verge of starvation in spite of a fine growing season; only two of them women.The natives were not all that comfortable with the presence of the colonists (and visa-versa), so it's not surprising their delegation was composed only of a lesser chief and a contingent of young men sufficient to overwhelm the colonists if necessary, and whose original intent may not have been all that certain. The young chief, apparently satisfied by what he found; sent out his young men for deer (a wild and extravagant splurge of energy to the colonists), and they promptly brought down, butchered and roasted 4 or 5 for the occasion, which no doubt saw the white men feeling rather small. Perhaps that was the point.The colonist's meager harvest did not get them through the following winter; it was the pity and generosity of their Native American neighbors. So I guess to do it right, you would have not only omit turkey, but beg food from your neighbors (once you got them to put down their rifles) for Thanksgiving dinner.I think prime rib will do just fine, if that's what you like.
