Looks like a butterfly doesn't it?
I bought a box of puff pastry and I did a few things with it. First I made the above cookies. Simple as can be, just smear fruit preserves over a sheet of pastry, roll in the sides, and cut into 1/4" slices bake at 400F for 20 minutes. They were best slightly cooled. The next day they were soggy.
Then, I loosely followed this recipe for a Tuscan-style Grilled Chicken Sandwich. I used a portion of puff pastry sheet for my bread, leftover rotisserie chicken and less cheese, pesto and mayo. It was really good. The pastry was a bit too flaky, but still good. I never thought to put artichokes on a sandwich before. They were so good. As was the pesto. They livened up an ordinary chicken sandwich.
With the remaining sheet, I made Pesto Twists. They were best hot from the oven. I made them after lunch and reheated them for dinner. They weren't as crispy.
