Ingredients
8 ounces flank steak, trimmed
1 tablespoon olive oil
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 medium yellow onion, thinly sliced
1 teaspoon butter
2 slices provolone cheese
2 slices crusty sandwich bread (such as ciabatta or baguette)
1 tablespoon mayonnaise
1 teaspoon Dijon mustard
Instructions
Preheat a grill or grill pan over medium-high heat.
Brush the flank steak with olive oil and season both sides with salt and black pepper.
Grill the steak for about 4-5 minutes per side for medium-rare, or until desired doneness is reached.
Remove the steak from the grill and let it rest for 5 minutes, then slice thinly against the grain.
While the steak rests, heat a skillet over medium heat and melt the butter.
Add the sliced onions and sauté for 5-7 minutes until they are soft and caramelized.
Toast the bread slices lightly on the grill or in a toaster.
Spread mayonnaise on one slice of bread and Dijon mustard on the other.
Layer the sliced steak evenly on one slice of bread, top with sautéed onions, and then place the provolone cheese over the onions.
Place the other slice of bread on top to complete the sandwich.
If desired, place the assembled sandwich back on the grill or skillet for 1-2 minutes to slightly melt the cheese.
Slice the sandwich in half and serve immediately.
