Method:
Put wheat berries into a large bowl, cover with at least 2 inches of water and set aside to let soak for 6 to 8 hours or overnight. Drain well.
Put 7 cups water into a medium pot and bring to a boil. Add wheat berries, reduce heat and simmer, uncovered, for about 50 minutes, or until cooked through. (Wheat berries retain a firm, chewy texture when cooked.) Drain and set aside to let cool.
Transfer wheat berries to a large bowl. Add walnuts, apples, raisins, parsley, vinegar, apple juice, salt, pepper, nutmeg, cinnamon, olive oil and lemon juice and mix everything together thoroughly.
