Tasty Paleo Salad Recipes: 21 delicious, healthy and easy to prepare 
salads. Suitable for special diets including Paleo, gluten-free, 
dairy-free, low carb by Elisabeth Peters

I really don't see a need for a recipe to make a salad. This is why 
salad bars are so popular. No recipe needed! Looking quickly through 
the book I find that vinegar appears. The author argues that since 
other paleo recipe include it then she can also. Though one can 
always use lemon juice instead.

The author admits that no legumes are paleo, but couldn't resist 
including some where we eat the green outside instead of the dried bean.

There is a lot of general advice before you get to the 21 recipes. 
And the recipes do provide useful ideas on salad making. And at the 
end there are a bunch of dressing recipes.

Yesterday's book that I reviewed is free for a second day. And there 
is a Master Resell Rights book free. This is a book where you buy it 
for $3.89 and then have rights to resell it for whatever you want. It 
is the fourth time that this same book has appeared on Amazon.
