Heat oven to 400 degrees. Peel, then slice fruit in small pieces. Place in a mixing bowl. Add vanilla, cinnamon and sugar; mix well. Let it sit for a few minutes allowing juices to come out of the fruit. Take the puff pastry and roll it out to make it a bit larger — not too much, Just stretch it so that it can hold more fruit. Spoon fruit onto the middle of the pastry and place one pat of butter on each. Pull the four corners of pastry together and press to close. Place on a baking sheet and bake about 15 to 20 minutes. Serve with ice cream or whipped cream.
