Decide what you need to learn more about.
Probably more recipes, cooking ideas, techniques, etc.
Possibly you want more background information/motivation to make the switch or continue along the same path.
Here are some resources I would recommend:
The why of it all:
Dr. Joel Fuhrman’s book Eat to Live
The China Study by Colin Campbell
The Green Smoothies Diet by Robin Openshaw
More recipe ideas:
This blog 🙂
Tammie’s blog, Simple, Healthy, Tasty
The Oh She Glow’s blog
How to Cook Everything Vegetarian by Mark Bittman – excellent mini cooking school in a book, lots of good techniques and information, use the recipes selectively of course – but, it’s such a large book that even cutting out all of those including dairy you are left with quite a selection.
