Recipe Information
Ingredients
- 1 pound Flank steak
- 2 tablespoons Olive oil
- 2 cloves Garlic cloves, minced
- 1 teaspoon Salt
- 1 teaspoon Black pepper
- 1 teaspoon Paprika
- 1 medium Red onion, thinly sliced
- 1 large Red bell pepper, thinly sliced
- 1 large Yellow bell pepper, thinly sliced
- 4 rolls Hoagie rolls or sub rolls
- 4 slices Cheese slices (Provolone or Swiss)
- 4 tablespoons Mayonnaise
- 2 tablespoons Butter
Instructions
In a small bowl, combine olive oil, minced garlic, salt, black pepper, and paprika. Rub the mixture evenly on both sides of the flank steak. Let it marinate for at least 10 minutes.
Preheat your grill or grill pan to medium-high heat.
Grill the flank steak for about 4-5 minutes per side for medium-rare, or longer for your preferred doneness. Remove the steak from the grill, cover with aluminum foil, and let it rest for 10 minutes before slicing thinly against the grain.
While the steak rests, heat a skillet over medium heat and add the butter. Once melted, add the sliced red onion, red bell pepper, and yellow bell pepper. Cook for 8-10 minutes, stirring occasionally, until they are softened and caramelized.
Preheat the oven broiler. Slice the hoagie rolls in half lengthwise and lightly toast them under the broiler for 1-2 minutes, watching closely to prevent burning.
Spread 1 tablespoon of mayonnaise on the bottom half of each hoagie roll.
Layer the sliced flank steak on top of the mayonnaise, followed by the caramelized onions and peppers.
Place one slice of cheese on top of the peppers, then return the sandwiches to the oven under the broiler for 1-2 minutes, just until the cheese melts.
Place the top half of the hoagie roll on each sandwich, slice in half if desired, and serve immediately.
