This is perhaps my favorite cook book. Michelle Tam offers a simple and charming introduction to the Paleo diet. The comic strips and photos of her children add a sweet touch. Lots of creativity comes through in all of her recipes. I recommend this cookbook more than any other. I particularly like her take on Vietnamese Beef Pho and the Slow Cooker Kahlua Pig.
