Reunion Steak Sandwiches

Every year, my grandma hosts a family reunion where these flank steak subs steal the show. They're topped with a "special sauce" that requires only three ingredients. For a quick dinner, serve them with coleslaw and macaroni salad from the deli.
  • Total Time
    Prep: 20 min. Grill: 20 min.
  • Makes
    6 servings

Ingredients

  • 1 beef flank steak (1-1/2 pounds)
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 2 tablespoons butter, softened
  • 6 sesame submarine sandwich buns, split
  • 2 medium tomatoes, thinly sliced
  • 1 medium onion, thinly sliced
  • 6 slices process American cheese
  • MUSTARD SAUCE:
  • 1/2 cup mayonnaise
  • 2 tablespoons Dijon mustard
  • 4-1/2 teaspoons Worcestershire sauce

Directions

  • Sprinkle steak with salt and pepper. Grill, covered, over medium-hot heat for 6-10 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Let stand for 5 minutes before thinly slicing.
  • Spread butter over inside of buns. Place the tomatoes, onion, sliced steak and cheese on bun bottoms. Broil 5-6 in. from the heat for 2-3 minutes or until cheese is melted. In a small bowl, whisk the mayonnaise, mustard and Worcestershire sauce until blended; spoon over cheese. Replace bun tops.

    Serve with plenty of napkins. They're 'finger-licking good'!
