I made chicken pie this week too. Super simple, just a crust on top, not a base as well, like the fruit one had.
Inside I made a packet up powder chicken soup up with half the amount of liquid suggested in the instructions (that way you get a lovely thick sauce).
Meanwhile I sauteed some leeks and cut up some leftover roast chicken into small pieces. I mixed the chicken and leek into the soup sauce and heated through (my chicken was frozen).
I poured the mixture into my pie dish and popped the crust on top, cooked in a hot oven (about gas mark 7/22oC/??F!) for about 18 minutes. (I know that's precise, I'd have left it for twenty, but Soph had a melt down and needed some attention, so I took the pie out then, rather than leaving it in and letting it burn!)
Next up, once I've bought some sausagemeat, is sausage pie! Also, I have photos of the apple and blackberry pie somewhere on the computer, so I'll share them once I've found them!
