What is the best way for me to reheat a Peter Luger's leftover? I don't want to cook the steak any more than it already is because I want to keep that medium rare but I just want to warm it up. I think the best thing to do first is to bring it to room temperature but what next? Blast it in the oven for a few minutes in some aluminum foil? I don't think putting it on the grill would be good. Maybe just throwing it in a hot pan for a few seconds? Please help.
