Warm 1 tablespoon of oil on medium heat in a big skillet. Toss in the green pepper and onions, sprinkle with salt and pepper, and cook until soft and golden. Take them out and set aside.

Turn up the heat to high and pour in the leftover oil. Throw in the steak strips, season with salt and pepper, and let them cook fast until browned. Split into portions when done.

Grab the bottom half of each roll. Pile up the steak, followed by the cooked veggies. Lay two cheese slices on top of each.

Slide the sandwiches under the broiler for a couple minutes until the cheese is melty and bubbly. Stick the top half of the roll on, and you're good to go!
