Preheat oven to 300 degrees F.
Slice the green peppers and onions. On medium heat, saute the vegetables with a little bit of olive oil. Cover the saute pan to let it steam a little, stirring often. When the vegetables have softened up a little, remove from pan and set aside.
Saute the meat with a little extra olive oil. Season with salt and pepper. Add the Worcestershire sauce and stir. Once meat is fully cooked, mix in the vegetables.
Open each roll lengthwise, add the meat and vegetable mixture. Put 2 slices of provolone cheese on top of the meat and put it in the oven on a baking sheet until the cheese melts.
