A snack-slice loaf of a food product and a method for providing food portions for snack trays in which the snack-slice loaf may include multiple overlying subunits. The overlying subunits are produced by sectioning a food block using cutting and sub-cutting, or perforation. The sectioned subunits can directly be placed into a food receptacle adapted to receive the sectioned subunits, without adding or subtracting food layers. The sectioned subunits may include stacks of processed cheese.
