I love puff pastry. If you keep some in your freezer, you can make a lot of great things with very little notice. It only takes about 30-40 minutes to thaw and is so versatile. Napoleons are usually desserts made with squares or rectangles of puff pastry and layered with pastry cream and fruit. I'm going to show you how to make savory asparagus napoleons but you can make napoleons with any filling you like. Get creative. I'm using asparagus because it's in season here now.
