Nothing is more comforting than coming home to this rich soup! I prepare the ingredients the night before and start the slow cooker on my way out the door in the morning. —Debra Kamerman, New York, New York
Place first 9 ingredients and 2-1/2 teaspoons salt in a 6- or 7-qt. slow cooker.
In a large bowl, mix egg and remaining 1/2 teaspoon salt. Add turkey; mix lightly but thoroughly. Shape into 1-1/4-in. balls; drop gently into slow cooker. Cook, covered, on low until vegetables and barley are tender, 6-8 hours.
