We doubled the recipe..thinking I was going to have some left over for 2 of us. Was I wrong. These were fantastic and really easy. Note to self: you can make these ahead of time but tossing the zucchini into a bag and leaving until ready to dump on the cookie sheet.
Drizzle vegetable oil into an aluminum or cast-iron pan, and heat the pan on the stove until the oil just begins to smoke. Add your flank steak to the pan. Cook one steak at a time. Sear each side of the flank steak for 2 to 4 minutes. Use fork or tongs to turn the flank steak once. Test the flank steak with a meat thermometer for at least an internal temperature of 145 F right before you anticipate the cooking time for your steaks to end.
Make certain the grill is extremely hot by allowing it to heat for 10 minutes before adding the steaks. Place the meat on the hottest portion of the grill and cook, undisturbed for 7 to 10 minutes per side for rare meat or 8 to 12 minutes for medium-rare.If you'd like the steaks to have cross-hatch marks, turn the meat 30 degrees after the first three to four minutes of cooking time has elapsed for each side.ortunately, you can avoid disappointingly tough, over-cooked porterhouse steaks by understanding the basic precepts of successfully cooking thick steaks on the grill -- how to prepare the meat in advance, how long to cook the cook the steaks and how to correctly judge their doneness.
