Best way to reheat rare beef

The roast beef for Sunday supper came out perfectly tender and medium-rare, but the sides took a little too long and now the roast is too cold to serve. To reheat it without cooking it further, place slices of meat in a ceramic pie dish or metal pan and cover with lettuce leaves, then broil for 2 minutes. The moist lettuce releases steam that helps keep the meat from overcooking and drying out.
