Preheat oven to 350°F. Unroll breadstick dough; cut each breadstick in half. Slightly stretch each breadstick and tie into a knot on each end to create a bone. Place bones on 2 large, greased baking sheets.
In small bowl, combine melted butter and Rustic Herb Seasoning; brush over breadstick bones and sprinkle with ¼ cup Parmesan cheese. Bake 13-15 minutes or until golden.
Meanwhile, combine crushed tomatoes, Mama Mia™ Marinara Sauce Mix and remaining ¼ cup Parmesan cheese in a small saucepan. Bring to a simmer and cook until heated through.
