Why did we do this, you ask??? My hubby, who isn't known for the love of reading books, is totally into David Suzuki's Green Guide, where he talks about Meat-Free Monday's as a way to cut down on carbon emissions.
Check out this link: http://www.guardian.co.uk/environment/2009/jun/15/paul-mccartney-meat-free-monday (Even though I'm not a vegetarian, I want the t-shirt Paul's wearing!) We thought it was a fun challenge and a great way to eat less meat as well. My only problem is that I don't think about what to make until Monday morning and then I'm rushing to come up with something that doesn't require 6-8 hours for beans to soak then cook! Oh well, it's still a fun challenge - you should try it!!
