I couldn't find any Peter Luger steak sauce in town, so I went with Shula's steak sauce. I thought it was a good substitute since we have a Shula's here in town. We both really enjoyed the at home version of the sandwich. We had a good time experimenting with Panini Month!
2 slices Pepperidge Farms Soft Sourdough bread
2 slices mozzarella cheese
5 slices deli roast beef
2-3 tps Shula's Steak Sauce
Spread butter on one side of each piece of bread. Put one piece of mozzarella cheese each non-buttered side of bread. Top one side with roast beef and steak sauce. Place the remaining slice of bread butter side up ontop of meat. Place butter-side down in heated grill pan. (I used a grill press to press the sandwich down in the pan) Flip and grill until golden brown.
