A relatively large food container includes a food box member in combination with a removable relatively small unfolded food container blank or insert. More specifically, the food box member includes an outside box member portion, the unfolded food container blank or insert is in a form of an inside box member portion, and perforations or slit cuts connect the outside box member portion to the inside box member portion. The removable unfolded food container blank is shaped and has fold lines so that when suitably manipulated it is adapted to form a triangularly-shaped small food box. The triangularly-shaped small food box is eminently suitable for storing left-over triangularly-shaped pieces or "wedges" of pizza.
