1/4 cup olive oil
1 tablespoon brown sugar
1 teaspoon ground ginger
4 cloves garlic, crushed
1 teaspoon salt
1/4 teaspoon black pepper
1 bunch green onions, sliced
1/4 cup pomegranate seeds

Arrange sweet potatoes and chicken pieces in a 9x13 inch baking dish. In a small bowl, mix together pomegranate juice, sherry vinegar, olive oil, brown sugar, ginger, garlic, and salt and pepper. Pour over chicken and sweet potatoes. Cover, and marinate for 1 to 2 hours, turning once.
