Gather all ingredients. Set oven rack about 6 inches from the heat source and preheat the oven’s broiler.

Mix steak and meat tenderizer together in a bowl.

Heat olive oil in a skillet over medium heat. Add onion and bell pepper; cook and stir until slightly softened, about 3 minutes.

Stir in steak mixture; cook and stir until flavors combine, about 3 minutes. Mix in Italian seasoning and pepper; add mushrooms. Cook and stir until steak is mostly browned, about 3 minutes.

Spoon steak mixture onto lower half of dinner rolls until covered; top with provolone cheese. Place onto a baking sheet.

Broil in the preheated oven until cheese is melted, 1 to 3 minutes; remove from broiler.

Place dinner roll tops onto melted provolone cheese; broil until tops are toasted, 1 to 2 minutes.

Enjoy!
