Flank Steak Sandwiches With Onions and Blue Cheese

1 1/2 pounds flank steak
2/3 cup bottled Italian dressing
2 tablespoons olive oil
2 large onions, halved and thinly sliced
1/2 teaspoon salt
Fresh-ground black pepper, to taste
6 large crusty sandwich rolls, halved
3/4 cup crumbled blue cheese

Place steak in a non-reactive large baking dish; pour dressing over. Marinate 20 minutes.

Heat a broiler or grill. Broil or grill steak, turning once, about 10 minutes until browned on outside but still pink in middle. Let rest on a cutting board 5 minutes.

Meanwhile, heat oil in a skillet over medium-low heat; add onions. Cook, stirring occasionally, 15 minutes until very browned and soft. Season with salt and pepper.

Cut steak across grain into very thin slices; place on roll bottoms. Top with cooked onions, blue cheese and roll tops. Makes 6 servings.
