Here’s a way to enjoy an old-fashioned steak sandwich. Use alittle bit of steak from the lean and tender fillet and top it with sautéed onions and mushrooms.
Heat the olive oil in a nonstick skillet over medium-high heat. Sprinkle both sides of the steak with salt and pepper. Place the steak in the pan and lower the heat to medium. Sauté the steak until well browned, 6 to 9 minutes, adjusting the heat if necessary to maintain a steady sizzle. Turn the steak and brown the second side, about 5 minutes.
