There's nothing wrong with a classic, but once in awhile, a few simple changes of ingredients can liven up a tried and true dish. A few tablespoons of curry powder and a package of puff pastry is all it takes to breathe new life into pot pie. Finishing the curry with a couple tablespoons of cream is optional if you're watching your waistline, but it's encouraged to add richness to the final product. If you do add the cream, make sure to give it another taste for seasoning afterwards.
If you're planning on having a busy Sunday, the filling can be made a day or two ahead (or even made a week or two in advance and frozen) and then simply assembled ad baked. A nice chutney and a green salad alongside and this updated classic makes a satisfying Sunday supper.
