Flank Steak Barbecue

Step 1
Whisk vegetable oil, soy sauce, vinegar, honey, garlic powder, ginger, and green onion together in a bowl; pour into a resealable plastic bag. Add flank steak, coat with marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator at least 4 hours.

Step 2
Preheat an outdoor grill for medium-high heat, and lightly oil the grate.

Step 3
Remove flank steak from marinade and shake off excess. Pour marinade into a small saucepan and set aside.

Step 4
Cook flank steak on the preheated grill until firm and reddish-pink and juicy in the center, about 5 minutes per side. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C) for medium-rare. Remove from the grill and cover with several sheets of aluminum foil. Let rest for 10 minutes, then slice thinly against the grain.

Step 5
While the steak is cooking and resting, bring marinade to a boil over medium-high heat. Reduce the heat to medium-low and simmer for 10 minutes. Pour over sliced steak to serve.
