Roast Beef Panini With Horseradish Mayo

“This recipe can be made in a panini maker, a George Foreman type grill or a ridged grill pan on the stove. Put foil around a slightly smaller pan and use it to press the panini down. Use whatever cheese you like or happen to have at home - a creamy Havarti goes nice with it - as well as leftovers from a roast or steaks.”
4 paninis
