Method:
Place wheat berries in a large bowl and cover with several inches of cold water. Let soak 8 hours or overnight. Drain and rinse wheat berries and place in a medium saucepan. Cover by several inches with fresh water and bring to a boil. Reduce heat to medium low, cover, and simmer until berries are tender and some break open, about 45 minutes. Drain well.
Place wheat berries, shallots, juice, celery, arugula, apricots and almonds in a large bowl and toss to combine. Let sit at least 1 hour to blend flavors before serving.
