I find pies often consist of too much pastry, which is why I prefer tarts. Instead of covering the contents in a thick shortcrust, you leave it open. For this vegetarian recipe I have also used filo pastry, which is a lot thiner and lighter than shortcrust, so leaves a lovely flaky base, and is a lot less fattening. Based on the ingredients I used each slice should be approximately 150 calories.
