It's Pi Day!

It's Pi Day, 3.14, and to my great delight, I've actually realised it before posting here - so you're getting a Pie post today. 

I am quite fond of pies, and sometimes think I should make them way more often, but... well... they do require either some work, or some suitable leftovers. Work as in "making the pie and the filling to go with it", or leftovers that can go into the pie shell with little or no modification, so there's only the dough, and then the baking, to do.

For weekday lunch (which is the thing I'm cooking stuff for), making both the dough and the filling is usually more time than I can fit into the schedule... which leaves leftovers to put into the pie. Sadly, that does not happen too often anymore either. The nicest leftovers (I think) that you can stick into a pie shell is some meat-based dish. Add in, maybe, some leftover potatoes and vegetables, the remainder of the sauce or make some if necessary, and off you go. However, we've reduced the amount of meat-based dishes that we eat over the course of the last years... and there's my problem with having leftovers. 

So, hm, maybe we should have the sweet version more often then, to make up for it - but there's so many nice cakes to bake...

Do you have favourite pie recipes? Sweet or savoury?
