Ingredients & Their Roles
For the Sandwich:
- 2 cups leftover steak, thinly sliced
Provides the protein base; use ribeye, strip steak, or sirloin for best flavor and texture. - 1 tablespoon olive oil
Used to sauté the vegetables and reheat the steak while keeping it juicy. - 1 small yellow onion, thinly sliced
Adds natural sweetness and depth with a caramelized texture. - 1 small green bell pepper, thinly sliced
Provides crunch and a slight bitterness that balances the richness of the steak and cheese. - 1 small red bell pepper, thinly sliced
Offers a mild, sweet contrast to the green pepper for added flavor complexity. - Salt and black pepper, to taste
Essential for seasoning and balancing the overall flavor. - 4 slices provolone cheese
Melts beautifully for that iconic creamy, gooey cheese pull. Can substitute with American or Cheez Whiz for variations. - 2 hoagie rolls or sub rolls
The foundation of the sandwich; choose a roll that’s sturdy but soft enough to bite through. - Optional: mayonnaise, hot sauce, or garlic butter
For spreading inside the rolls and adding extra moisture and flavor.
Step-by-Step Instructions
1. Prep the Steak
- Slice the leftover steak as thinly as possible against the grain. This ensures tenderness and easier layering in the sandwich.
2. Sauté the Vegetables
- In a large skillet, heat olive oil over medium heat.
- Add sliced onions and both bell peppers. Cook for 6–8 minutes, stirring occasionally, until soft and lightly caramelized.
- Season with a pinch of salt and pepper.
3. Reheat the Steak
- Push the veggies to one side of the skillet. Add the sliced steak to the other side.
- Stir occasionally and cook for 2–3 minutes until warmed through. Avoid overcooking to keep the steak tender.
4. Melt the Cheese
- Toss the vegetables and steak together in the skillet.
- Lower the heat and layer provolone slices over the mixture. Cover with a lid or foil to help the cheese melt, about 1–2 minutes.
5. Toast the Rolls
- While the cheese is melting, split the hoagie rolls and toast them on a griddle or in the oven until golden and slightly crisp.
- For added flavor, brush the inside of the rolls with garlic butter or mayonnaise before toasting.
6. Assemble the Sandwiches
- Once the cheese is melted, scoop the steak and veggie mixture into the toasted rolls.
- Serve immediately while hot and melty.
Why This Recipe is Loved

Pro Tips for Perfection

- Melt cheese thoroughly: Covering the skillet helps create that signature gooey cheese layer.
- Toast the roll properly: A lightly crisped hoagie adds necessary texture and prevents sogginess.
