Back in Melbourne circa 2010/11, Jodie, Jared and I used to run a [monthly vegan mentoring group][vegan-month]. I have gone back through the mailing lists and collected much of the curriculum and information from the program into this single document, so that I can distribute it more widely. The program was designed not just to get you through the first month nutritionally, but to expose you to a variety of foods and ideas that may be new to you. It emphasises that veganism is a shift sideways, not a sacrifice.
