Place each piece of chicken between 2 sheets of heavy-duty plastic wrap, and flatten to 1/4-inch thickness, using a meat mallet or rolling pin. Combine 1 teaspoon curry powder and next 3 ingredients in a shallow dish; dredge chicken in flour mixture. Set aside. Coat a nonstick skillet with cooking spray; add oil. Place over medium-high heat until hot. Add onion and garlic; saute 3 minutes. Push onion and garlic to side of skillet; add chicken, and cook 2 minutes on each side or until browned. Add remaining curry powder, tomatoes, and raisins; reduce heat to medium, and cook 4 minutes, turning chicken once. Place chicken on a serving platter; spoon sauce over chicken. Top with yogurt; garnish with parsley, if desired. Yield: 4 servings (serving size: 3 ozs. chicken, 1/4 cup plus 2 tablespoons sauce, and 1 tablespoon yogurt).
