I've been told that it's hard to find a savoury pie in the US, so my choice is probably going to sound strange to most cause over here, when ya talk about pie it's usually savoury. Although, we do have some sweet ones too, but not the range that ya have there.
My favourite savoury pie is steak, bacon and cheese!
I've only really had apple and sweet pumpkin pies. The pumpkin would be my first choice.
