The romaine lettuce is more plentiful than the basil, which adds crunch, but not the flavor combo that you'd expect on a caprese. All in all, it's a pretty plain sandwich.
The veggies include peppers, cucumbers, tomatoes, and red onions, adding plenty of crunch to the sandwich. The salty and creamy feta adds Mediterranean flavor to the dish.
Sliced red onions and salt and pepper round out the sandwich. It comes on black pepper focaccia bread, but it’s better with sourdough or even French bread.
