Our family tradition has always been for Thanksgiving Dinner to have only foods we grew or foraged ourselves. It felt just right to preserve the intention of gratitude for the bountiful earth.
HOWEVER one year we moved to a new home the week before Thanksgiving. There was just enough time to grow some sprouts. The wild foods were scarce but enough to bring flavor and teas to the table. (Fortunately for us my parents invited us to join them for a "normal Thanksgiving" at their home later in the day)
