In reply to Deadeye:
Our house went vegetarian 2 or 3 days a week for cost reasons some years ago, but it's really hard to do as for someone used to cooking meat, it needs a lot of effort to find new recipes and learn new ingredients. We struggled on for a year or so even after the finances recovered, but with the same vege recipes every week, which was dull and tedious.
Last year we went vege for a month to force us to think creatively about vege food and increase the variation. Now it's really easy for us to go three or four days a week without meat and with some thought we can go 'full time', which we do for a few weeks at a time in each season. We still love meat and buy less, better quality cuts.
Some changes became permanent, so no more meat in sandwiches at home or if I have to buy one out. It's always cheap meat, so I'll save my 'quota' for something really nice at home. I'd recommend going vege for a month to anyone trying to cut down on meat.
The Part-Time Vegetarian is a great recipe book, we bought it as a 'treat' before our first month off and it's nice to have something physical to look through when finding new recipes. And you can add meat to any of the dishes if you want.
