1/2lb grilled, medium-rare flank steak, sliced into thin strips
1 large red bell pepper
1 sweet yellow onion
4 ciabatta rolls
12 sprigs fresh basil, chopped
8 slices Provolone cheese
Drizzle of olive oil, salt, and pepper
Slice pepper and onion into thin, long strips. Drizzle a little olive oil, salt and pepper and toss.
Heat a grill and place pepper and onion slices, grilling for a few minutes until wilted and charred. Remove from the grill.
Slice ciabatta rolls in half, place a slice of cheese on both sides of the bun. On one side of the bun, place 4-5 strips of flank steak, peppers and onion, on each roll, then sprinkle with a little basil.
Cover with the other slice of cheese and bun.
Place on a panini press and grill for several minutes until the cheese melts. Enjoy!
