Oh I'm sorry, I didn't realise steak pie was "local" to us! The filling is a bit like a thick stew. Do you know stew? A casserole perhaps. Chunks of steak, tasty gravy, and as Laurie says, Steak and Kidney is very popular too, but steak pie doesn't need to have kidney in it. The whole thing is topped off with a flaky pastry and is absolutely wonderful!
