Heat the oil in a large pan. Add the steak and cook until it’s lightly browned. Toss in the peppers, onions, and mushrooms. Cook until the veggies are soft and the onions are translucent.

In a small bowl combine the mayonnaise and garlic. Slice your rolls in half and spread with the mayonnaise. Top with your meat and veggie mixture and a slice of cheese. Broil for 3 minutes or until the cheese has melted.
