1 to 1 1/2 pounds steak (I substitute with chuckeye roast beef)

4 oz cheddar cheese, sliced

1/2onion， thinly sliced

oil for grilling

salt to taste

freshly ground black pepper

2 bread rolls (authentic Philly cheesesteak calls for hoagie or torpedo rolls. I can’t find it in local grocery store and I substitute with Italian rolls)

Chicken stock

soy sauce

sugar

oyster sauce

sesame oil

Thaw the frozen beef overnight in fridge. Thinly slice it with a meat slicer .
