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.
If you are cooking uncovered it should be 8-11 minutes. A 1 inch boneless rib eye, tenderloin, or top loin steak should be cooked for 6-8 minutes on the George Foreman Grill (covered) at 350 degrees F to 375 degrees F for medium rare. If you are cooking uncovered it should be 8-11 minutes.
