Ingredients

Instructions

  • Trim the steak of visible fat and gristle, and cut it into 1-inch squares.
  • Clean the mushrooms and halve or quarter them if larger. You want them about the same size as the steak chunks.
  • Mix the steak and mushrooms with the garlic, Dijon mustard, 2 tbsp of olive oil, dehydrated onion flakes, and Worcestershire sauce. Mix well to coat.
  • Add 1 tbsp of oil to a large skillet and preheat the pan over fairly high, but not scorching hot, heat. Working in two batches, add the meat and mushroom mixture, stirring it a few times to allow for even browning. Cook it for approximately 2-3 minutes for medium-rare beef, another minute or so for more well-done beef. Test the doneness of the beef by cutting into one of the cubes, and cook longer if necessary. Remove from the pan and set aside.
  • Cook the remainder of the beef in the remaining oil, taking care not to overcook the beef.
  • Serve with your favorite sides!
