CHEESE SAUCE FOR STEAK SANDWICH RECIPES

Steps:

• 1. Tightly roll the eye round steak into a torpedo or log shape. Wrap tightly in plastic. Place log in freezer for 45 minutes to firm the beef into a tight but not frozen texture.
• 2. Remove plastic, and working quickly, use an electric knife to slice the beef into paper-thin strips, almost shaving the beef. If this does not work well, use a sharp knife and cut the beef into the thinnest slices possible, then flatten the slices using a meat tenderizer. Refrigerate slices until ready to cook.
• 3. Peel and halve onion. Slice into paper-thin half moon pieces. Halve the peppers, remove and discard seeds, and then slice into thick wedges.
• 4. Warm 2 tablespoons of the oil in a large skillet over low heat. Add onions and cook 8 to 10 minutes, until caramelized and softened, stirring frequently. Do not allow them to brown. Transfer onions to bowl; add pepper to same skillet, still over low heat. Cook peppers 10 to 15 minutes, until soft and tender, flipping often. Transfer to bowl with onions. Season onion-pepper mixture to taste. Cover bowl to keep warm.
• 5. In a clean skillet, warm the remaining 2 tablespoons oil over medium heat. Cook the beef in 2 batches, until lightly browned and cooked through, stirring often. Add olive oil if necessary.
• 6. To serve: Pile beef strips, peppers and onions and cheese slices inside a hero roll.

Steps:

• Place steak in freezer for 30 to 45 minutes; this makes it easier to slice the meat. Remove the meat from the freezer and slice very thinly.
• Heat griddle or grill pan over high heat. Brush steak slices with oil and season with salt and pepper. Cook for 45 to 60 seconds per side.
• Place several slices of the meat on the bottom half of the roll, spoon some of the cheese sauce over the meat, and top with the mushrooms, onions, and peppers.
• Melt butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1 minute. Slowly whisk in the warm milk, and cook, whisking constantly until thickened, about 4 to 5 minutes. Remove the mixture from the heat and whisk in the provolone and Parmesan until combined; season with the salt and pepper.
• Heat oil and butter in a large saute pan over high heat. Add the mushrooms and cook until the mushrooms are golden brown. Stir in the parsley and season with salt and pepper.
• Heat butter and oil in a large saute pan over medium heat. Add the onions, season with salt and pepper, and cook slowly until golden brown and caramelized, stirring occasionally, approximately 30 to 40 minutes.
• Heat the oil in medium saute pan over high heat. Add the peppers and cook until soft. Season with salt and pepper.
