Chicken Avocado Sandwiches

I was watching Giada cook for the millionth time in my life the other day and she made this amazing looking Neopolitan sandwich..it made me want to make it and see if it tasted half as good as it looked..she said it was a light sandwich but it was NOT light since it required puff pastry instead of bread which is DEFINITELY not light..but it was, indeed, AMAZING! She made it as a 3 layer but I figured it was going to be too large to eat from top to bottom so I made it 1 layer instead..came out extremely tasty..
