Grilled Flank Steak

"Grilled Flank Steak is a tender beef steak marinated in a balsamic vinegar-based marinade and seared to perfection. It is delicious in steak fajitas, on a steak salad with bleu cheese, or with a loaded baked potato with a side of grilled asparagus. This is one of my favorite grilled beef recipes, and it could not be any easier. The steak is best when allowed to marinate for at least six hours; therefore, a little advanced preparation is needed. If you like this recipe, try New York strip steak, Steak Diane, Swiss Steak, and steak bites. "
