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.
In an oven safe pan (I used my 10 inch cast iron) over medium high heat melt 1 tablespoon of butter or use oil. When hot, sear both sides of the steaks for 2-3 minutes. Sear to the close to the final color you want.Transfer pan to the preheated oven. If you don't have that, you can season with a little course salt, pepper and granular garlic powder. 2  Or anyway you want. 3  In an oven safe pan (I used my 10 inch cast iron) over medium high heat melt 1 tablespoon of butter or use oil. 4  When hot, sear both sides of the steaks for 2-3 minutes.
