Preheat the oven to 350 degrees F.
In an 11 x17 (or 9 x 13) casserole dish place the bottom halves of the King's Hawaiian rolls.
Spread the Philadelphia Spicy Jalapeno Cream Cheese Spread over the rolls.
Sprinkle the round steak with sea salt and freshly cracked black pepper to taste.
In a large skillet over medium high heat, add the oil. When hot add the steak slices and cook for about 3 minutes. Turn and cook for another minute or two. Watch carefully because these thin slices of steak cook very quickly.
Remove steak, and layer the steak over the jalapeno cream cheese covered rolls.
In the same skillet as you cooked the steak, add the onions, peppers, and mushrooms. Cook for about 5 minutes or until the vegetables are soft.
Spoon the cooked vegetables over the steak on the rolls.
Place 6 to 7 slices of provolone cheese over the top of the vegetables.
Spread the Spicy Jalapeno Cream Cheese spread on the top halves of the rolls.
Place the top halves of the King's Hawaiian rolls on top of the provolone cheese.
In a small bowl, stir together the melted butter, minced garlic, jalapeno mustard and worcestershire sauce. Brush over the tops of the rolls.
Cover the pan with foil.
Bake in a 350 degree oven for 10 minutes. Remove the foil and bake uncovered for 10 more minutes.
Remove from the oven, slice into 12 sandwiches and serve hot.
