Not really a Philadelphia Cheese Steak

Make a marinade of balsamic vinegar, a little soy sauce, red wine, a little olive oil, lots of garlic, some thyme, whole black peppercorns, and some ground pepper. Marinate beef overnight in the refrigerator. Put beef on a foil-lined baking tray in a single layer. Dice some pickled garlic and mix in with beef. For 1 pound of beef, 10 heads or so. Broil beef for 20 minutes or until juices run clear. Slit french rolls and fill with beef and garlic mixture. Grate on top mozzarella cheese. Put filled rolls in toaster oven or under broiler until the cheese melts (a minute or two) and serve.
