Grilled Chicken with Sweet Potato-Lime Sauce Juice of 1 lime 1/4 cup fresh orange juice 1/2 teaspoon turmeric (optional) 1/2 teaspoon ground cumin 1/2 teaspoon ground coriander Salt and freshly ground pepper, to taste 4 boneless, skinless chicken breasts (about 1 1/4 pounds total), washed and patted dry Sauce: 1/2 cup water 3 garlic cloves, peeled, minced 1 teaspoon minced fresh ginger 4 green onions, washed, ends removed, sliced 1/2 teaspoon ground cumin 1/2 teaspoon ground coriander 3/4 pound (about 1 medium) sweet potato, peeled and diced small 1 (14 ½-ounce) can fat-free, reduced-sodium chicken broth Juice and grated rind of 1 lime Few drops of lemon juice 1/4 cup fresh chopped cilantro Additional green onion slices and cilantro sprig for garnish if desired In a small baking dish or pie plate, mix the orange juice, turmeric, cumin, coriander, salt and freshly ground pepper. Add chicken, turning to thoroughly coat it. Set aside while preparing the sauce. In a large skillet, place the water, garlic, ginger, green onions, cumin, coriander and sweet potato. Cover and cook over medium heat about 7 to 10 minutes. If mixture seems to dry, add more water as necessary to prevent the ingredients from sticking to the pan. Uncover and cook about 3 minutes or until the sweet potato is tender. Transfer the mixture to a blender or food processor and process until smooth. Return to the skillet and whisk in the chicken broth, lime and lemon juices and chopped cilantro. Keep the sauce warm over low heat. Remove the chicken from the marinade; discard the marinade. Grill the chicken in a grill pan over medium heat about 5 minutes per side depending on the thickness or until chicken is cooked through. Alternately, pan sauté or broil the chicken breasts. Serve garnished with green onion slices and cilantro. Makes 4 servings.
