Begin by gathering your ingredients and prepping them for a seamless cooking experience. Thinly slice the ribeye steak against the grain.

Heat a tablespoon of olive oil in a large skillet over medium-high heat. Add the chopped onions and bell peppers, sautéing for about 5 minutes until translucent.

Once the vegetables are tender, push them to one side of the skillet and add the sliced ribeye steak. Season with salt and pepper and cook for about 4 minutes.

Combine the sautéed vegetables and beef, stacking slices of provolone cheese on top, then cover the skillet with a lid and let sit for 2 minutes.

While the cheese melts, slice open your hoagie rolls. Spoon the cheesy beef and vegetable mixture into each roll.

Serve the sandwiches warm, pairing them with crispy fries or a fresh salad for a complete meal.
