You can't have a Thanksgiving dinner without turkey. Why do we eat turkey at Thanksgiving? It's not the cheapest way to feed a crowd, it's not the easiest to cook, and takes hours depending on method. It seems that with our modern access to meat and produce from around the world any time of year tradition would be set aside for convenience. Alas, like it or not, turkey is and will probably always be the center of a Thanksgiving dinner.
