Cheesesteak Hoagies

2 lbs steak (cheap steak- I used skirt steak) FREEZE for 20 minutes before slicing.
1 medium yellow onion (I used a vidalia)
1 green pepper
4 hoagie rolls
2 tsp black pepper
1 tsp salt
provolone cheese (6 slices cut in half)
1-2 tbsp butter

Slice the onion and pepper in a food processor. Place in a bowl. Slice the meat in the food processor. Heat the butter in a pan on medium- medium/high heat. Once melted, add the steak. Cook steak for about 4 minutes with the salt and pepper. Add the pepper and onion. Cook for another 4 minutes. Put lid on pan and let steam about 5 minutes. Spoon mixture over the hoagie rolls. Top each hoagie with 1 1/2 slices cheese. Microwave until cheese is melted- about 30 seconds. OR (as I prefer) place in the oven (around 450*) for about 5 minutes, until the cheese is melted and the hoagie roll is just starting to crisp.
