After a full day of fun, it’s time for a hearty plate of steak and potatoes. When buying for the weekend, keep in mind it’s a good idea to call ahead and order two flat-iron steaks, because there is only one flat-iron steak per steer. Flank or tri-tip steaks make fine substitutes. You’ll serve roughly two-thirds of the steak for dinner Saturday night and use the rest for Sunday brunch. Creamy fingerling potatoes will serve double duty for Sunday brunch and peppery arugula salad offers a refreshing bite to the plate.
