Baking the dip in the actual bread shell makes it a very attractive dish, and it's very easy to clean up. Every time I serve this, people can't believe how healthy and veggie-filled it is. —Ella Homel, Chicago, Illinois

Editor's Note: Reduced-fat or fat-free mayonnaise is not recommended for this recipe. If any of the dip does not fit in bread shell, bake, uncovered, in a greased small baking dish until heated through.
