Weeks before Pesach, my mother’s freezer is efficently stocked with dozens of these pretty two-toned rolls. (My mother even graciously prepared this roll for the photo shoot). This recipe is my mother’s original creation and has been passed to many people who have made it a must-have Pesach staple. For additional variations, substitute sweet potatoes with either sauteed mushrooms and onions or sauteed minced meat and onions for a chic and innovative shepherd’s pie.
