It appears I was a bit vague in my post and I appreciate the input to help me clarify it.
It was asked if I sliced the naan bread in half. The answer is no, I used two pieces of naan bread.
Each slice, on one side, was sprayed with EVOO and then sprinkled the chopped, fresh rosemary.
The sides with the rosemary on it faced toward the inside of the sandwich where the meat, cheese and tomato was.
I hope this clarifies things.
