The Philly Cheesesteak - the undisputed culinary jewel of Philadelphia. A perfect ratio of that holy trinity - beef, cheese and bread. We've gone that step further and thrown gravy all over it, turning the original lone sarnie into a more sociable slider tray.
- Preheat the oven to 180°C/360°F.
- Heat a little oil in a deep sided frying pan with a lid and brown the steak all over, then remove from the pan with a pair of tongs.
- Add the onions and peppers and fry until soft, then add the mushrooms and keep cooking until a little of their moisture has evaporated. Add the garlic and stir until fragrant.
- Pop the beef back in and add the flour, salt and pepper.
- Pour over the beef stock and the Worcestershire sauce and bring to a simmer, then cover with a lid and cook until the beef is soft and the gravy nice and thick, around an hour.
- Arrange the bottom halves of all the slider rolls on a tray and top with cheese, then use a slotted spoon to add the beef mixture, followed by more cheese. Top with the top of the rolls and spoon gravy all over them.
- Bake for around 10 - 15 minutes until they are cooked through and the cheese has melted.
