Michele: Meat pie is just what it sounds like - a pie filled with meat (mostly beef as far as I can tell) and sauce. Every town has at least one bakery that sells these pies. Some bakeries offer fancy varieties with vegetables like peas or onions. The one in the photo is a frozen meat pie heated in the microwave for my lunch... yum. You are supposed to eat meat pie with tomato (to - mah' to) sauce but I like mine naked.
One of our favorite dinners is lamb snag (sausage). The butcher sells them with rosemary seasoning and they are really yummy and inexpensive. We have thoroughly taken advantage of the opportunity to eat Australia lamb while we've been here. It is awesome. Definitely something we will miss back in the US.
I realize that quite of few of my vegetarian friends my be reading this and not convinced. If you are the type of vegetarian you can wiggle your boundaries around a bit I highly recommend you try a little bit of lamb snag and meat pie when you are in Australia.
