Step 1

Preheat the broiler. Heat the oil in a large sauté pan set over medium heat.

Step 2

When oil is shimmering, add the peppers and onions and cook, stirring occasionally, until softened, about 8 minutes. Season with 1 teaspoon of the ranch and stir well until fully combined; remove and set aside.

Step 3

Using the same pan, add the steak and sprinkle the remaining seasoning evenly over the meat. Sauté, stirring occasionally, until meat is fully cooked, about 5 minutes.

Step 4

Pile a quarter of the meat on each of four hoagie rolls; then top with the pepper and onion mixture. Distribute cheese over the top.

Step 5

Place the sandwiches open faced on a sheet pan and broil until the cheese is melted and the buns are slightly toasted, about 2–3 minutes. If desired, drizzle with additional Ranch dressing. Close the rolls and serve warm.
