Oh my goodness. These were divine. This picture truly does not do them justice! I found this recipe over at Fifteen Spatulas. I'm sure we will be making these again soon, these would be perfect for a Saturday night watching football!
3/4 pound strip steak
1 tbsp olive oil
2 tbsp butter
1/2 a softball sized onion (thinly sliced)
1 small green pepper (thinly sliced) (we don't like peppers so I didn't use them)
8 oz mushrooms (chopped)
8 slices of provolone
salt and pepper
4 hoagie rolls, sliced in half about 3/4 of the way down
Place the strip steak in the freezer for about 30 minutes. This makes it much easier to slice. Prepare your other ingredients while it's chilling. In a pan add the olive oil and butter. Add the onions with a bit of salt and pepper. Cook for 15 to 20 minutes or until translucent. Add the peppers if using and cook for 15 more minutes. Remove and add mushrooms to pan. Slice the steak now. Heat oven to 350. Continue cooking mushrooms until brown and soft. Add to the onion and pepper mixture. Add the steak to the pan and toss, letting it cook for about 30 seconds on each side. Turn the heat off and add the onions, peppers and mushrooms back to the pan. Divide into 4 sections and top with 2 slices of cheese per section. Once the cheese is melted, scoop each section into one hoagie roll, wrap in foil and place in the oven for 15 minutes. When they are done in the even remove from foil and enjoy.
