It doesn't get much better than a sandwich and fries combo, but this recipe takes that perfect pairing up a notch. Thinly sliced beef, layered with peppers, mushrooms and onions, all topped with cheese on a toasted bun - is your mouth watering yet? And better still, serve it up with garlic parmesan tater tots for the ultimate lunch or dinner (and if you want to dish it up for breakfast too, we won't judge).
