squab pie is a favourite of ours.
I haven't got the recipe handy, but it is something like this:
Layer of sliced spuds in the bottom of a casserole dish. Layer of sweated chopped onions. Layer of sliced cooking apples (needs to be something sharpish - bramley will be fine) small sprinkle of brown sugar, layer of cubed lamb, or you could use chops if you like, more apples, more onions, topped of with another layer of sliced spuds. A few dollops of butter and a sprinkle of brown sugar on the top and whack it in the oven until the spud is cooked.
Really really good.
Bear in mind that there are lots of dishes that say to use pork or beef that you can just as easily use lamb in.
