Slice the ribeye steak, onion, and green bell pepper.

In a skillet, heat olive oil over medium heat. Add the sliced onion and bell pepper, and sauté until softened, about 5 minutes.

Add the sliced ribeye steak to the skillet. Season with salt and pepper. Cook until the beef is browned and cooked through, about 5-7 minutes.

Place a slice of provolone cheese on top of the beef and vegetable mixture. Cover the skillet to melt the cheese, about 2 minutes.

Spoon the beef and cheese mixture into each hoagie roll. Serve immediately.
