This can be a great meatless meal or it will do nicely as a side dish to any meat. I recommend pearl barley (it is the most common varity) as it cooks up better in a crock pot without becoming gummy and sticky.
Mix all the ingredients except green onions and nuts on a 4-6 qt crockpot or slow cooker.
Cover and cook on low heat for 6 to 8 hours or until barley is tender.
Stir in green onions and pine nuts.
*Totoast pine nuts, bake uncovered in an ungreased shallow pan at 350 degrees for 10 minutes, stirring occasionally until golden brown or cook in an ungreased heavey skillet over medium-low heat 5 to 7 minutes, stirring frequently until browning begins and them stirring constantly until golden brown.
