A system comprising a tenderizing apparatus with a fluid reservoir provides users an efficient way to simultaneously tenderize and marinate food. The tenderizer with a fluid reservoir generally includes a fluid outlet or valve and a tensioning element. A fluid reservoir receives marinade. Activation of the system by applying downward pressure releases marinade into an injector. The injector is inserted into the target food. Substantially simultaneously, activation results in at least one projection penetrating the surface of the target food. When downward pressure is released, the injector and projection retract. A first portion and a second portion are separated for easy cleaning. A removably attached first portion cover and third cover provide easy storage.
