I came across this useful website
for people saving money Down Under while I was looking for the info about the $21 a week grocery challenge. It seems they only do it for a week and mainly live out of what's in the kitchen, so not terribly helpful for living on a minimal amount long term. But some of the recipes look good so will try them out. I signed up for the free newsletter, and if it is any good I may look at paying the nz$47 membership.
Today I had pasta with the frozen mixed veg for my first meal, and pancakes with bananas tonite. I didn't get the oil hot enough before pouring the batter in, so they stuck to the pan and were a bit messy, but they tasted good.
