Rooted in gratitude for a good harvest, Thanksgiving is a day of togetherness and feasting for many Americans. It is a time to wipe the dust off Grandma’s delicious recipe cards or to head to the Deli Fresh grocery aisles for savory string beans and pumpkin pie. For many, Thanksgiving is the purest and most important holiday of all, unblemished by the commercialism that threatens to tarnish Christmas and other celebrations.
