The food carrier has a central vertical support panel with a handle and a pair of trays with beverage cup holders attached to the central support panel. A folded side-wall structure can be unfolded to start the formation of the trays, and a folded bottom panel or two-panel structure unfolds into the side-wall outline to stabilize the side-wall and hold the carrier erect while it is resting on a flat surface thus to make unfolding and loading the carrier quicker and easier. An auxiliary tray can be slipped into the central vertical support to hold solid foods, and both beverages and solid foods can be carried. Advantageously, the auxiliary tray can have substantially the same structure as the first carrier unit, except it has no beverage-receiving holes. It can be mounted to ride "piggyback" on the first carrier, or it can be used alone.
