Steak and Cheese Sandwich

1. Put a pan on high heat, add in the olive oil, onions, bell peppers and season it with salt and black pepper. Sauté for about 8 to 10 minutes until golden and caramelized. Then remove it from the pan. 
2. To the same pan, put in the shaved steak, season it with the Montreal steak seasoning and cook on high heat until cooked through, it should take about 10 minutes. 
3. Once everything is cooked, start assembling the sandwiches: add the steak, the sautéed onions and peppers, top it with your favorite cheese (pepper jack was used here). 
4. Transfer the sandwich into a tray and place them in the oven and broil just until the cheese melts. Then add in your favorite toppings (mayo, tomato, lettuce) and enjoy!
