Cheesesteaks

1 lb thinly sliced beef (either raw or deli roast)
1/2 lb sliced cheese (provolone and/or mozzarella)
2 cups sliced mushrooms
1 small onion, chopped
4 hoagie rolls
olive oil
salt and pepper
hot pickled peppers (optional)

1. in a skillet, sauté the onion in oil over medium-high heat until tender. add mushrooms - season with salt and pepper - and continue to sauté until browned. set aside in a bowl.
2. slightly toast hoagie rolls in a toaster oven or on the skillet.
3. cook and/or brown beef in the skillet. add a few slices of cheese to the meat and mix in. separate as much of the beef you would like for one of the sandwiches and place a slice of cheese on top. let it melt. do this for however many cheesesteaks you want to make (they're just as good the next day - so leftovers are great).
4. when the cheese on top is melted lift the meat and cheese onto the toasted roll. top with mushrooms and onions (and peppers). enjoy!
