  • 1 lb (454 g) flat-iron or beef flank steak
  • 2 tbsp (30 mL) butter

  1. Sear steak in a skillet or grill pan to medium rare, about 3 min per side. Set aside.

    Kind of soupy

    Very savoury sandwich and pretty easy to make. The amount of broth and dijon together was kind of soupy. Would go less than 2 cups each. Other than that it was delicious!
