I use the walmart great value cheese steak beef but you can use whatever you prefer. The measurements of everything is entirely up to how you like your cheese steak. On the stove top in a skillet on medium high add beef, onion, salt and pepper. In a separate pot add oil and bring to heat. (You want to cook this like a deep fry.) Add hash browns. Cook until browned. Set aside on a paper towel to drain oil. Add meat and cheese to rolls and put in oven on broil until cheese melts. Add the hash browns and serve.
