For years Mum made a savoury slice using sausage meat which she’d take on picnics, a recipe that I’ve made lots of times as well.  This sausage pie is a bit different though with the layers of sausage meat, tomato and onion topped with egg.  It’s sort of an adaption of an egg and bacon pie. I haven’t made it, but as it says it would be great hot or cold.
