For those of you who like to celebrate Pi Day with pie (and who doesn't?), here's a great recipe for caramel apple pie for two. It makes four small pieces -- perfect for dessert tonight and breakfast tomorrow (hey, it contains fruit). If you have another pie recipe you're planning to make but need a smaller pie crust, this recipe makes enough for a 6-inch pie or tart or two individual pies. Either way, Happy Pi Day!
