Thanks for the ideas

Wow! We (NZers) pay three times that much for decent meat - even mince is about $11kg at the moment. I guess that is the biggest problem with NZ - we have lots of great fresh foods, but they all get exported!

Fruit and bread, on the otherhand, is always fresh and plentiful.

Could anyone tell me what soy protein isolate is? I asked about it at the healthfood shop, but the saleswoman had no idea. Can I just substitute it with soy flour?
