Remove the roast from the bag and harvest the juices into a microwaveable container (or small sauce pan). If desired, process the juices as explained here and set aside. 
Butterflying the steak
Stand the steak on its lean edge. Use the slicer knife to split the steak "almost" in half--just enough so that the steak can be folded open as shown.
Dust the surface of the steak with powdered egg white. Note: fresh egg white can also be used--beat one egg white well with 1 oz/25 ml water, and use to moisten the surface. 
Moisten the powdered egg whites to create a sticky surface. 
Sprinkle with your favorite seasonings, with no more than 1 teaspoon of salt as a component. 
Turn the steak over--note the fold in the steak--at service, this will be the "bottom" of the steak, so as not to be visible. 
Repeat the process with the powdered egg whites. 
Mist again with water. 
Repeat the seasoning process and spray lightly (or drizzle) with oil. 
Turn the steak over and spray (or drizzle) with oil. Service
Heat the cast-iron broiler pan (or sauté pan) to 350 F/176 C. Spray or drizzle the pan with a few drops of oil and wipe dry with a dry cloth or paper towel. Place the steak in the pan and sear for 30 seconds or until grill marks appear. Turn the steak 90 degrees and sear another 30 seconds. Turn the steak over and continue searing for another 45 seconds or until the desired color is achieved.
Melt the pats of butter on top of the steak and sprinkle with chopped parsley. If desired, add a few drops of demi-glace. Drizzle the red oak lettuce and grape tomatoes with extra virgin olive oil and salt and pepper.
