This Grilled Flank Steak with Tomatoes, Red Onion, and Balsamic recipe contains flank steak, extra virgin olive oil, tomatoes, red onion, garlic powder and more.
The sandwich starts with thick rustic Italian bread, hearty enough to support the fillings but still tender. There are three kinds of cheese in play...and the toasty bread is infused with garlic flavor by rubbing it with cut garlic cloves.
