Step 1: Add all of the ingredients to a medium-size pot and cook over low heat stirring often until hot and thick. Keep warm.
Step 2: Meanwhile, add 1 1/2 tablespoons of clarified butter to a large frying pan or flattop over medium-high heat and cook the onions until lightly browned and soft, about 10 minutes. Set to the side. If you decide to to also use peppers and mushrooms, cook them in the same manner as cooking the onions.
Step 3: Add the remaining 1 1/2 tablespoons of clarified butter to the pan and add in the shaved steak.
Step 4: Cook for 2-4 minutes or until lightly browned and cooked throughout.
Step 5: Add 1/2 of the cooked onions to the top of the beef. Season with salt and pepper (or Montreal seasoning). (When seasoning, be very careful not to go over. It can easily become too salty and a little goes a long way. Remember that it will be topped with cheese which is salty of its own nature). Distribute the seasoning by flipping here and there with a spatula until well distributed.
Step 6: Add the sliced buns cut side down onto the other side of the pan or flat top to heat up and lightly toast.
Step 7: Evenly divide the sliced cooked steak between the lightly toasted buns and top off with the remaining caramelized onions (and peppers/mushrooms, if you decide to use these) and cheese sauce. Pepper sauce (aka; hots) to taste can also be used.
