A side-loading pendulum slicer for slicing short and/or oddly-shaped food products. The pendulum slicer has an aperture in the upstream side of the product holder through which food products are injected. A loading conveyor holds large numbers of food products that are sequentially and individually loaded onto an injecting conveyor that injects the food products through the aperture and into the product holder. A weight that is raised above the aperture is lowered onto the food product to compress the food product against a thickness tray while the product holder reciprocates through a blade adjacent the thickness tray. Slices are removed from the food product and conveyed away for use.
