Salt and freshly ground black pepper

1 cup sliced onion

1 cup sliced baby bella mushrooms

1/4 cup reduced fat mayonnaise

1 tablespoon Dijon mustard

1 cup arugula leaves

1 whole wheat baguette (6 ounces needed)

Remove to a cutting board and sprinkle with salt and pepper to tase. Add the onion and mushrooms to the skillet. Saute 2 minutes. Return the steak to the skillet and continue to cook 5 minutes. A meat thermometer should read 135 degrees for medium rare. Remove the skillet from the heat. Place the steak on a cutting board and let it rest for 5 minutes. Thinly slice the steak.

Meanwhile cut the baguette in half lengthwise and toast the halves in a toaster oven or under a broiler. Mix the mayonnaise and mustard together. Spread over the cut sides of the baguette. Place the sliced steak over the mayonnaise on the bottom half of the baguette. Spoon the onion and mushroom over the steak and add the arugula on top. Place the top half of the baguette on top. Cut the baguette in half to form two sandwiches. Then cut each half in half and serve on two dinner plates. Garnish with sliced tomatoes on the sides of the plates.
