This was stocking stuffer from my mother in law. I've been a vegetarian for years now, so I don't really need a guide to it at this point, but I was interested to see what McGuire would include...and there's a lot packed into this tiny book! Everything from nutritional information, cooking times for beans and grains, health info, environmental info, meal plans, how to handle eating out and travel, how to handle social situations... And it seems pretty spot-on and related in a way that never comes across as preachy or judgy. There are no actual recipes, but a lot of general rules of thumb and processes so you don't even always need a recipe.
While this certainly wasn't revolutionary for me, there were a few things I hadn't thought of (there's a bit on getting stuck in ruts and trying new things that really spoke to me) and some very useful advice. This would be a great place for a beginner to start, as it can all be read in one sitting, but still contains a ton of super practical info.
Bravo, Mom-in-law!
