When you need an impressive appetizer that you can “casually whip up" for friends (or bring to your friend's cousin's parents' house on Thanksgiving), buy a box of frozen puff pastry. Roll the sheets into rounds, create a pocket of spanakopita-inspired filling, then put your arts and crafts skillz to work. Don't worry if your tarte looks a little wonky going into the oven: Once it emerges, we guarantee that everyone will want to take a picture, even if it means waiting a few more minutes to start tearing off those cheesy, buttery twists. And that mini circle that's leftover in the middle? Consider that a chef's treat. When you're buying puff pastry, the two most common brands are Dufour and Pepperidge Farm. Either is fine, and both boxes come with two sheets of pastry. See recipe.
