3 tablespoons of olive oil
2 cups of thinly sliced onion
3 garlic cloves minced
1 teaspoon of dried oregano
1 red bell pepper thinly sliced
1 green bell pepper thinly sliced
1/2 teaspoon of salt divided
1/4 teaspoon of black pepper divided
1 1/2 pounds of boneless rib steak thinly sliced
4 hoagie rolls split horizontally
16 slices of provolone cheese
- Heat 1 tablespoon of the oil in a large nonstick skillet over medium heat. Add the onion, garlic, and oregano; cook, stirring occasionally, until softened, about 7-8 minutes. Add the bell peppers, 1/4 teaspoon of the salt, and 1/8 teaspoon of the pepper and cook until softened, another 7-8 minutes. Transfer mixture to a bowl and return the skillet to the stove.
- Season the steak with the remaining 1/4 teaspoon of salt and 1/8 teaspoon of black pepper. Heat 1 tablespoon of the oil in the skillet; add the steak and cook until no longer pink, about 2-3 minutes. Transfer to a plate.
- Arrange the bottom halves of the hoagie rolls on a work surface. Top each with 2 slices cheese, 1/4 of the onion mixture, 1/4 of the steak, and 2 more slices of cheese. Set the top half of each roll over the cheese. Press down each sandwich with your hand slightly. Brush the outside of bread with remaining 1 tablespoon oil.
- Heat a nonstick grill pan over medium. Place two sandwiches at a time on the grill pan; set the skillet on top and press down to press the sandwiches. Cook 3-4 minutes or until the bottom of sandwiches is golden. Flip the sandwiches and again top with the skillet and press down. Cook until the cheese is melted and the top and bottom of the sandwiches are golden. Repeat with the remaining sandwiches. To serve, cut each sandwich in half on an angle.
