Instructions

  1. In order to make the meat easier to slice, place it in the freezer for 30-45 minutes.
  2. Remove the meat from the freezer and cut it into very thin slices.
  3. Sauteed peppers: Heat the oil over high heat in a medium saute pan. Add all peppers and cook until soft. Season sauteed peppers to taste with salt and freshly ground black pepper.
  4. Caramelized onions: Heat the oil and butter over medium heat in a large saute pan. Put in peeled, halved Spanish onions, freshly ground black pepper, and salt. Slowly whisk, cooking until caramelized and golden brown, about 30-40 minutes.
  5. Sauteed mushrooms: Heat the oil and butter over high heat in a large saute pan. Add the cremini and shiitake mushrooms and cook until they are golden brown. Stirring occasionally, add parsley and season to taste with salt and freshly ground black pepper.
  6. Provolone sauce: In a medium saucepan over medium heat, melt butter and whisk in flour over 1 minute. Add whole milk to the flour mixture, whisking constantly until thickened - approximately 4-5 minutes. Remove from milk heat and stir in the provolone and Parmesan. Season provolone sauce with salt and freshly ground black pepper to taste.
  7. Heat grill pan or griddle over high heat. Brush oil over steak slices and season with salt and pepper to taste. Cook slowly, 45-60 seconds per side.
  8. Put the steak on the bottom half of the roll. Place provolone sauce over the meat and then top it with peppers, onions, and mushrooms.
  9. Salt and pepper to taste.

  • If you're short on time, you can skip the step of freezing the meat. Just slice it as thinly as possible.
  • You can make the cheese sauce beforehand and reheat it.
  • The recipe calls for whole milk, but you can substitute lower fat milk mixed with cream.
