Steak Sandwich

I don't know how you make your sandwich, but I make mine on garlic cheese bread and with balsamic mushrooms and onions. You really can't go wrong. 

First, I bake garlic bread for about 12 minutes. Then pull it out, break open the bag and make sure the butter is spread around well. Top the bread with parmesan cheese, freshly ground black pepper, and oregano. Broil on low for a few minutes, until the cheese melts and the top of the bread is slightly browned.

Meanwhile, grill your steak to whatever grade you like. I prefer medium-rare. Take the steak off the BBQ and wrap in foil while you prepare the rest of the well.

Around the same time I start the bread, I'm sauteing some white onion and mushrooms. Once they are nice and tender and slightly caramelized, toss in about a teaspoon or two of balsamic vinegar and cook until reduced.

Slice up your steak, arrange it on the garlic bread (I use about a quarter per person) and top with your balsamic onions and mushrooms.
