I bought The No-Salt, Lowest-Sodium Cookbook right after I was diagnosed with hypertension.

I never actually used the cookbook, but instead opted to make more things from scratch, read more labels and select things based on their sodium content.

So in no particular order:

Cajun Season Chicken with Mustard and Lemon (p 96)
Scrambled Eggs with Peppers and Mushrooms (p 127)
Leon's Pita Salad (p 192)
Hummus (p 142) with Whole Wheat or Pita Bread (p 275)
