In a large skillet, heat the olive oil over medium-high heat.
Add the sliced onions and green bell peppers to the pan. Sauté for about 5-7 minutes, until they become tender and slightly caramelized. Remove from the pan and set aside.
In the same skillet, add the thinly sliced ribeye steak. Sprinkle with garlic powder, black pepper, and a pinch of salt. Cook for 3-5 minutes, turning occasionally, until the steak is browned.
Stir in the Worcestershire sauce and mix well.
Return the sautéed onions and bell peppers to the skillet, mixing everything together for another minute until heated through.
Preheat your oven to 350°F (175°C).
Slice the hoagie rolls open, but not all the way through. Lay them on a baking sheet.
Divide the steak mixture evenly among the rolls and top each with shredded provolone cheese.
Bake in the oven for about 5-7 minutes, or until the cheese is melted and bubbly.
Remove from the oven, garnish with chopped parsley, and serve immediately.
Notes
Serve the sandwiches on parchment paper or wooden boards, alongside a side of crispy fries for a complete meal experience.
