Girlled Vidalia Onion and Steak Sandwiches

1 1/2 lbs flank steak, trimmed
6 1/2 in thick slices of Vidalia onion
6 Kaiser rolls
cooking spray

Steak Marinade:

3/4 c cola
2 T red wine vinegar
1 t ground black pepper
1/2 t salt
1/2 t ground chipotle chile pepper (I use red pepper flakes instead)
4 crushed garlic cloves
1 crushed bay leaf

Dressing:

3/4 c minced arugula
1/2 c mayonnaise

To prepare steak, combine the marinade ingredients in a large zip-lock bag.. Add steak. Seal and marinade in the refrigerator for 2 hrs, turning occasionally. Remove steak from bag, reserving marinade. Pour reserved marinade into microwave-safe bowl. Microwave on high for 2 mins or until boiling. Set aside.

Prepare the dressing by combining the arugual and mayonnaise. Set aside.

Grill steak on a grill rack coated with cooking spray. Grill 8 mins per side for medium-rare steak. Remove steak from grill. Cover and let stand for 5 mins. Place onion slices on grill rack. Grill 4 mins per side, basting occasionally with reserved marinade.

Cut steak diagonally across grain into thin slices. Spread 2 T dressing on Kaiser rolls. Add tomato if desired. Makes 6 sandwiches.
