Chicken Marinara

In a skillet, saute onion and garlic in oil until crisp tender. Stir in the tomato sauce, parsley, salt, oregano, basil and pepper. Bring to a boil. Reduce heat; simmer, uncovered, for 10 minutes. Place flour in a resealable plastic bag. Add chicken, one piece at a time, and shake to coat. In a skillet, cook chicken in butter until lightly browned on all sides. Place skin side up in a greased shallow 1-1/2-qt. baking dish. Pour sauce over chicken. Cover and bake at 350 degrees F for 35 minutes. Uncover; sprinkle with Parmesan. Bake 5-15 minutes longer or until chicken juices run clear. ');
